1、電源技術(shù)方案:
小功率電源使用穩(wěn)定、耐用,外觀小巧,方便靈活擺放,還可根據(jù)客戶要求設計外形;大功率采用并機型冗余模塊電源系統(tǒng),高頻開關(guān)電源技術(shù),IGBT功率控制模塊,RS485標準通訊接口、PMW脈沖寬度調(diào)制技術(shù)。
2、電源概述:
本廠電源采用IGBT功率控制模塊,高頻開關(guān)電源技術(shù),為穩(wěn)定大功率電源的輸出,采用并機型冗余模塊電源系統(tǒng),在提高輸出穩(wěn)定性的基礎上,簡化了設備的檢修維護過程,提高了設備可持續(xù)工作能力,可插拔式模塊電源能夠?qū)崿F(xiàn)“故障不停機,維修不誤工”,極大的減少了客戶因設備故障問題造成的生產(chǎn)損失。根據(jù)客戶要求,RS485能夠良好的實現(xiàn)與計算機通話,完成并網(wǎng)控制。電源所采用系統(tǒng)相同,相互之間可并聯(lián),實現(xiàn)并聯(lián)輸出。
3、關(guān)于規(guī)格:
我公司對電源規(guī)格型號,直接采用電源參數(shù),比如1000A12V電源即為輸出直流電流1000A、直流電壓12V的高頻電源。
4、電源使用環(huán)境:

9、冷卻
關(guān)于電源的冷卻,本電源可采用風冷以及水冷兩種冷卻方式,風冷簡單,但是噪音會比較大,水冷要比風冷穩(wěn)定;躍陽生產(chǎn)的水冷電源適用自來水,一般水冷電源對水質(zhì)有要求,最好使用去離子水;而躍陽水冷電源解決了這個問題,躍陽生產(chǎn)的水冷電源水壓可以調(diào)高,防止產(chǎn)生水垢后使管道堵塞。
主要特點:
1.過流保護:當電源工作過程中發(fā)生過流現(xiàn)象時,系統(tǒng)能有效保護設備安全。
2體積小、重量輕:體積與重量為可控硅整流器的1/5-1/10,便于您規(guī)劃、擴建、 移動、維護和安裝。
3.節(jié)能效果:開關(guān)電源由于采用了高頻變壓器,轉(zhuǎn)換效率大大提高,正常情況下較可控硅設備提高效率10%以上,負載率達70%以下時較可控硅設備提高效率 30%以上。
4.輸出穩(wěn)定性高:系統(tǒng)反應速度快(微秒級),對于網(wǎng)電及負載變化具有極強的適應性,輸出精度可優(yōu)于1%。開關(guān)電源的工作效率高、所以控制精度高,有利于提高產(chǎn)品質(zhì)量。
5.輸出波形易于調(diào)制:工作頻率高,其輸出波形調(diào)整相對處理成本較低,可以較方便的按照用戶工藝要求改變輸出波形。這樣對于工作現(xiàn)場提高工效,改善加工產(chǎn)品質(zhì)量有較強作用。
6.缺相保護:當電網(wǎng)故障造成設備缺相運行時,系統(tǒng)會自動關(guān)機。
7.電壓保護:允許電網(wǎng)變化范圍為380±10%V,當電網(wǎng)超出允許范圍是自動調(diào)節(jié)脈寬,保證設備正常運行。
8.過熱保護:當通風系統(tǒng)堵塞、通風系統(tǒng)內(nèi)部故障、風機溫度過高,電源自動停止工作,同事發(fā)出報警信號。
9.操作簡單:可遠端控制高頻直流電源可帶非線性負載,近控遠控兼?zhèn)洹?/span>

艾默生、華為、中興、動力源等通信系統(tǒng)電源數(shù)量的配置的核算方法 艾默生、華為、中興、動力源等通信系統(tǒng)電源的配置可根據(jù)下面的公中興ZXDU68 S601高頻開關(guān)電源機柜 式來計算選擇: (1)計算所需開關(guān)電源總輸出電流 I OUT 方法一: IOUT =Ifz +0.2C10 (A),式中 Ifz 為所需最大負載電流(A); C10為蓄電池額定容量(Ah)。0.2C10為考慮電池均充時時最大限流值。 方法二: IOUT = (Ifz +0.1C10 )/(0.7~0.8),式中0.7~0.8是考慮系統(tǒng)安全運行的裕量系數(shù)。0.1C10 為考慮電池均充時時最大限流值。 (2)選擇整流器規(guī)格,計算所需整流模塊數(shù)量 N ,N ≥I OUT /I Z,,式中I Z為整流模塊的額定輸出電流(A);N取整數(shù)。 (3)按 N+1 原則配置整流模塊數(shù)量,當求得的N≤10時,配置整流模塊數(shù)為N+1 ;當求得的N>10時,每10個模塊加配1個。 以方法為例(方法二同樣代入公式即可): 已知某基站直流負載電流Ifz為110A,配置的每個開關(guān)電源整流模塊輸出額定電流、I Z為50A,電池容量為300A,計算這個基站的開關(guān)電源需配置多個個整流模塊?正常需開啟多少個整流模塊?

Accounting methods for the distribution of power supply in communication systems such as Emerson, HUAWEI, ZTE and power sources
The configuration of the power supply for communication systems such as Emerson, HUAWEI, ZTE and power sources can be calculated according to the following formula:
(1) the total output current I OUT of the switching power supply is calculated.
Method one: IOUT =Ifz +0.2C10 (A), Ifz is the required maximum load current (A); C10 is the rated capacity of the battery (Ah). 0.2C10 is always the biggest limiting value of battery charge account.
Method two: IOUT = (Ifz +0.1C10) / (0.7~0.8), in which the 0.7~0.8 is the margin factor that takes into account the security of the system. 0.1C10
As always the maximum current limit of battery charge account.
(2) choose the specifications required for the calculation of rectifier, rectifier module number N, N = I OUT /I Z, I Z, in the rated output current of rectifier module (A); N integer.
(3) according to the number of N+1 configuration principle of rectifier module, when the N is less than or equal to 10, the number for the N+1 configuration of the rectifier module; when the N>10, each of the 10 modules with 1.
Take the method as an example (method two can be replaced by the same formula):
It is known that the DC load current of a base station is Ifz 110A, and the output current of each switching power rectifier module is 50A, and the battery capacity is 300A. The number of rectifier modules of the base station's switching power supply needs to be configured with more than one rectifier module. The output current of the rectifier module is Ifz. The output current of the rectifier module is I. How many rectifying modules do you normally need to open?
IOUT =Ifz +0.2C10
=110+0.2* 300
=170A
N =I OUT /I Z
=170/50
=3.4
N should be added to 1 decimal, rounding, N=4
The number of modules should be opened: 5 (if only 4, one module is bad, when the power is out of power, the battery is dissatisfied and will lose).
Number of cold standby modules: 1
The number of modules should be configured: N+1=54+1=6 (N>10, adding 1 for every 10 modules)
Special emphasis: do not open all the spare modules, so as to avoid wasting electricity and shorten the module life.

從整體性能來看,我國通信電源水平與國外同類產(chǎn)品相比,存在一定的差距。主要差距在工作的可靠性、穩(wěn)定性和技術(shù)性能等方面。因此,組織力量研制開發(fā)具有自主知識產(chǎn)權(quán),技術(shù)含量高的新一代通信電源,對振興民族工業(yè)、提高產(chǎn)品的質(zhì)量和競爭力,提高開發(fā)隊伍的研究水平具有重要的意義,也會帶來顯著的經(jīng)濟效益和良好的社會效益。二、通信電源的器件、電路拓撲與控制技術(shù)對通信電源來說,其核心部分是開關(guān)變換器,而開關(guān)變換器的技術(shù)進步主要體現(xiàn)在器件、電路拓撲和控制技術(shù)方面有所突破,因此,應用這些相關(guān)技術(shù)的最新成果到通信電源中,是提高通信電源的技術(shù)性能、質(zhì)量和可靠性的重要措施之一?梢詮囊韵碌囊恍┓矫孢M行初步的探討:1、從電路的拓撲結(jié)構(gòu)和器件方面來說,目前通信電源的變換電路拓撲結(jié)構(gòu)主要采用雙單端電路,半橋電路和全橋電路,各有化缺點。一般認為,在中、小功率場合,采用雙單端電路或半橋電路是適宜的;在大功率場合則來用全橋變換電路。雖然也出現(xiàn)一些新的變換電路電路拓撲,如低輸入、輸出紋波的CuK變換器,傳輸比高的Buck-Flyback變換器等等,但由于軟開關(guān)技術(shù)等一系列新技術(shù)的興起,電路拓撲改造降溫,在目前的情況下,電路的拓撲變化不大。從器件的角度來說,功率電子器件從半控器件(晶閘管),發(fā)展到了各種各樣的自關(guān)斷器件,并且已經(jīng)有所謂的功率集成電路(PIC)的出現(xiàn),其驅(qū)動模式也從電流型驅(qū)動模式發(fā)展為電壓型驅(qū)動模式。在目前的通信電源中,由于應用場合的不同,場效應管(MOSFET)和絕緣柵控晶體管(IGBT)是使用得較多的兩種器件。一般來說,場效應管驅(qū)動容易,開關(guān)頻率高,具有正的溫度系數(shù),易于并聯(lián);其不足之處是受到其結(jié)構(gòu)限制,耐壓不高,且體電阻過大(雖然并聯(lián)可以降低其電阻)。通常認為,在中、小功率范圍內(nèi),采用場效應管是適宜的,其開關(guān)頻率很高,可以降低整個電源的體積、重量和成本,驅(qū)動可以采用簡單的脈沖變壓器,可以通過管子并聯(lián)的方法來解決其容量不足的問題,其耐壓值較低也適合單相交流輸入的情況。IGBT輸出容量大,耐壓高,體電阻小,是大功率開關(guān)電源的首選器件,但其開關(guān)頻率低,驅(qū)動雖然也是電壓型,要比場效應管復雜一些,其溫度系數(shù)是負值,不易并聯(lián),并且在關(guān)斷時存在著電流拖尾現(xiàn)象。所以IGBT與場效應管,兩者各有所長,有不同的應用場合,隨著技術(shù)的進步,兩者器件方面的欠缺,可以通過電路中采用適當?shù)拇胧﹣斫鉀Q。另一個值得注意的問題是,由于目前電源開關(guān)頻率很高,要求設計人員對高頻功率變換電路必須有足夠的認識,對器件的高頻特性有足夠和清楚的了解,穩(wěn)態(tài)分析和動態(tài)分析并重。尤其是分析它們的失效機制或損壞機理,以采取合理的保護措施來說,還必須深入了解這些功率器件的不同開關(guān)機理和工作特點。此外,在高頻時,系統(tǒng)、線路和負載的各種等效阻抗和低頻時差別很大,并且在較高的開關(guān)頻率下,系統(tǒng)能量分布很容易改變,或者局部產(chǎn)生振蕩,或者在某個幅值段或某個頻率段產(chǎn)生振蕩。所有這些,在低頻時是不必考慮的。因此,設計人員對電力電子器件本身特性的了解就成為電路設計成功與否的一個重要原因之一。對器件了解得不深或理解錯誤而導致電路失敗的事是屢見不鮮的,加深對器件的認識是設計成功的一個首要條件。不過,目前一些新技術(shù)的出現(xiàn),如軟開關(guān)技術(shù)換流等,降低了變換電路對分布參數(shù)的敏感性,拓寬了器件的安全工作區(qū),也在一定的程度上降低了對器件的要求。 2、從電磁元器件的角度來說,通信電源中大量使用磁性器件,比如各種各樣變壓器、電抗器、 電流互感器、濾波或諧振電感等,它們對電路性能有重要的影響?傮w而言,對磁性材料要求是具有寬的溫度范圍,高頻損耗小,矯頑力低,導磁率高;而變壓器繞制則通風散熱好,且繞組要用多股細線并繞,或者用銅皮繞制,以減少高頻時集膚效應。由于功率器件性能的改善,以及軟開關(guān)技術(shù)等的采用,使得電源開關(guān)損耗大為下降。因此降低高頻變壓器和其他磁性器件的損耗已成為提高開關(guān)電源效率的一個主要因素,增大輸出變壓器功率的關(guān)鍵是磁性材料的選擇與結(jié)構(gòu)的確定。欲使變壓器結(jié)構(gòu)緊湊、損耗小,應選擇飽和磁感應強度、電阻率及脈沖磁導率較大,且?guī)Р暮穸刃〉拇判圆牧。同時,采用絕緣強度高的材料作為線圈間的絕緣,以進一步提高能量傳輸效率。 目前,高頻開關(guān)電源中,一般采用鐵氧體磁性材料作為變壓器的磁心。鐵氧體的電阻率高,高頻損耗小。但它的飽和磁感應強度太低,所以磁心面積需要較大,影響耦合系數(shù)的提高,且鐵氧體是壓鑄而成的,具有易脆性,制造大規(guī)格磁心有一定的困難。非晶態(tài)合金是近年發(fā)展起來的新材料,位錯的遷移性很低;沒有晶界,無各向異性;無阻止磁疇運動的障礙;易磁化,其磁感應強度高;電阻率大,對渦流阻力大,矯頑力小,能耗低。但以U型供貨的磁心磁感應強度大大降低,而以環(huán)形供貨的磁心則繞制線圈比較困難。此外,其尺寸不夠大,要滿足大容量的開關(guān)電源需求,還有待進一步解決。由于非晶態(tài)合金兼有電阻率高和飽和磁感應強度大的優(yōu)點,高頻損耗小,導磁不導電,因此,它是高頻開關(guān)電源將來較為理想的磁性材料?赏M一步減小電源的體積和重量,降低能耗,提高效率。近期國內(nèi)外在非晶態(tài)合金的基礎上,經(jīng)過處理,使其變成微晶合金軟磁材料,其性能比非晶態(tài)合金更高,更適合制作開關(guān)電源變壓器和電抗器。國內(nèi)已有來用這些新型微晶材料研制開關(guān)電源。但也應當指出,在高頻開關(guān)電源中使用的磁性器件有許多新的特點,例如頻率從工頻到幾百千赫,功中興ZXDU68 S601高頻開關(guān)電源機柜 率從毫瓦到幾十千瓦甚至幾百千瓦,激磁電流可能是非正弦的,磁化不一定對稱。在某些電路中需采取去磁措施等等。在高頻下運行的磁性器件材料、結(jié)構(gòu)、模型、設計、工藝、損耗、發(fā)熱等多方面問題,尚需繼續(xù)深入探索研究,以獲得較為滿意的解決。
3、開關(guān)變換器的新控制技術(shù)與新方法,器件發(fā)展到一定程度后,要進一步提高產(chǎn)品的性能,必須采用新的控制方法和新的技術(shù)。目前,新的控制方法和技術(shù)主要有軟開關(guān)技術(shù)和功率因數(shù)校正技術(shù)。民主均流控制技術(shù),電流模式控制技術(shù),本脈沖(one-cycle)控制技術(shù)等等。軟開關(guān)技術(shù)是指功率器件在零電壓或零電流條件下進行換流。因此,軟開關(guān)技術(shù)可以降低功率器件的開關(guān)損耗,提高系統(tǒng)的開關(guān)頻率,降低變換器的體積和重量,使得系統(tǒng)的輸出紋波減少,并且可以克服變換電路對寄生分布參數(shù)的敏感性,降低系統(tǒng)的開關(guān)嗓音,展寬系統(tǒng)的頻帶,改善系統(tǒng)的動態(tài)性能。而功率國數(shù)校正技術(shù)通過有源校正的方法,使得網(wǎng)側(cè)電流波形跟蹤電壓波形,這樣,把掛在電網(wǎng)的開關(guān)電源變成一個接近純電阻的負載,不但可以抑制網(wǎng)側(cè)諧波電流,改善網(wǎng)側(cè)功率因數(shù),降低電源的高次諧波產(chǎn)生的噪音和污染,提高電網(wǎng)的質(zhì)量,減少無功功率的流動和達到節(jié)能的效果,也使得電源的電磁兼容性能力得到了加強。民主均流控制技術(shù),既能實現(xiàn)電源模塊的自動均流,又可以實現(xiàn)電源模塊的冗余,電源模塊的退出與增加均不影響系統(tǒng)的正常工作,均流母線的開路,短路以及模塊的損壞都不會影響系統(tǒng)其他模塊的正常工作,是目前最優(yōu)秀的均流方法。電流模式控制技術(shù)則在以往電壓反饋控制的基礎上,增加電流反饋控制,在對電壓控制的基礎上,對電流也進行動態(tài)的控制,使得能夠逐個脈沖對電流進行控制,一方面能加快系統(tǒng)的動態(tài)反應能力;另一方面,也使得變壓器的偏磁情況、負載的均流、電源模塊的過載或短路保護等得到明顯的改善。而本脈沖控制技術(shù)是一種大信號的非線性控制方法,在每一個周期向取開關(guān)變量,經(jīng)過積分器的積分與給定電壓比較,其誤差經(jīng)過放大后動態(tài)地調(diào)節(jié)變換器占空比的大小,由于每個周期內(nèi)的占空比值只與該周期的開關(guān)變量有關(guān),且開關(guān)變量(電壓或電流)的平均值在一個周期內(nèi)到達新的穩(wěn)態(tài),使得開關(guān)變量(被控制量)的平均值和控制量無論是穩(wěn)態(tài)和動態(tài)都沒有誤差,具有良好的抗干擾能力和快速的動態(tài)響應能力。該技術(shù)既可用于PWM控制,又可用于PFM控制;既可用于硬開關(guān)控制,又可用于軟開關(guān)控制;既可用于電壓模式控制,又可用于電流模式控制;既可用于電流連續(xù)的工作模式控制,又可用于電流不連續(xù)的工作模式控制;是開關(guān)變換器控制方式發(fā)展的一個重要方向。將這些先進技術(shù)應用到通信電源中,將會使得通信電源性能水平上一個新的臺階。在軟開關(guān)變換電路中,有變頻控制的(PPM),也有恒頻控制的(PWM).由于恒頻控制方式要優(yōu)于變頻控制方式,恒頻軟開關(guān)技術(shù)已成為軟開關(guān)技術(shù)的主流。其中,相移控制的全橋變換電路,綜合PWM技術(shù)和軟開關(guān)技術(shù)的優(yōu)點,在大范圍內(nèi)實現(xiàn)PWM控制,實現(xiàn)輸出電壓或電流的大范圍無級調(diào)節(jié),而在功率器件換流瞬間,實現(xiàn)零電壓開關(guān)換流,已成為最有前途的軟開關(guān)變換電路拓撲。但目前國外廠家相移控制軟開關(guān)電路也有不足之處,主要是變換電路滯后橋臂零電壓開關(guān)范圍窄,拓寬其軟開關(guān)范圍是其進一步廣泛應用的前提,各國學者一直在努力,提出一系列改進方法,主要集中在三個方面:一是采取措施,拓寬滯后橋臂的零電壓開通范圍; 二是把滯后橋臂構(gòu)造成零電流關(guān)斷范圍大的軟開關(guān);三是原邊的開關(guān)管和副邊的整流二極管同時實現(xiàn)大范圍的軟開關(guān)。目前,在這幾方面都取得了很大的進展,為軟開關(guān)技術(shù)在通信電源中的廣泛應用打下良好的基礎。在功率固數(shù)校正電路方面,單相的PFC技術(shù)也已非常成熟,其電路通常采用升壓比(boost)電路,采用電壓、電流雙閉環(huán)控制的方法,主要采用平均電流控制的方法。其中電壓環(huán)用來穩(wěn)定輸出電壓,電流環(huán)使得電流跟蹤電網(wǎng)的正弦波形。由于電流環(huán)的給定是電壓環(huán)輸出與電網(wǎng)整流后的正弦半波(100Hz)的乘積,因此電壓環(huán)的帶寬不能超過10OHz,否則電流波形跟蹤不好,一般設計頻帶是30Hz以下,同時,為了保證整個控制回路的增益與電網(wǎng)的幅值無關(guān),需要進行必要的前債補償,F(xiàn)在市場已有成熟的控制芯片,既有來用硬開關(guān)控制的,也有來用軟開關(guān)控制的。而三相功率因數(shù)校正技術(shù)上比較復雜,雖然國內(nèi)外相應的研究成果也很多,但要應用在大功率開中興ZXDU68 S601高頻開關(guān)電源機柜 關(guān)電源方面,尚需作進一步的研究和探討。
在控制模式方面,既有采用電壓模式控制的,也有來用電流模式控制的。電壓模式是單環(huán)控制,電流模式控制是雙環(huán)控制,這兩種控制模式各有化缺點,不存在誰取代誰的問題,要根據(jù)電源的具體實際要求來決定采取合適的控制方式。不過,電流模式控制技術(shù),可以較好地解決大功率電源的并聯(lián)問題。在新技術(shù)方面,近來開關(guān)變換器發(fā)展起來的本脈沖控制是最值得注意的方向之一。不過,目前尚未見到有本脈沖控制技術(shù)的通信電源產(chǎn)品出現(xiàn)。 與此同時,世界上許多著名的電子公司為了適應功率電子學發(fā)展的浪潮,不斷推出適應各種新型控制技術(shù)的芯片,美國的UNITRODE公司是其中一個杰出代表,其所開發(fā)的芯片既有電壓模式控制的,又有電流摸式控制的,覆蓋了功率電子學所有的應用領(lǐng)域。其中,與開關(guān)電源密切相關(guān)的芯片主要有相移控制系列芯片,單相硬開關(guān)功率因數(shù)校正系列芯片,單相軟開關(guān)功率因故校正系列芯片,開關(guān)電源負載均流系列芯片等等。這些性能良好的軟開關(guān)控制、功率固數(shù)校正芯片和其他相關(guān)芯片的研制成功,為軟開關(guān)技術(shù)和功率因數(shù)校正技術(shù)以及其它新技術(shù)在通信電源的應用奠定了基礎。 三、通信電源的電路模型和理論分析目前開關(guān)變換器的分析方法主要有數(shù)字仿真方法和解析建模方法。數(shù)值數(shù)字仿真的方法(如SPICE等等)準確度高,可以得到系統(tǒng)的響應特性和波形,但沒有明確的物理意義;解析建模方法有明確的物理意義,對設計和分析具有指導意義,但需要作一定的假設。一般認為,電力電子系統(tǒng)仿真主要有三個層次,即器件層次,電路層次和系統(tǒng)層次,在不同的設計階段,關(guān)心的側(cè)重點不同。器件層次的仿真主要用于研究器件的開、關(guān)過程,這往往需要設計人員對器件有較深刻的認識,提出比較合理的器件模型參數(shù),以深入了解分布參數(shù)對器件開、關(guān)過渡過程的影響,為設計和分析提供了一定的依據(jù)。電路層次的仿真主要是對其宏觀波形進行分析,此時,一般把器件當作是理想開關(guān),主要是對電路的拓撲結(jié)構(gòu),控制方法,電路特性等等進行分析。系統(tǒng)層次的仿真主要是著眼于系統(tǒng)的控制方式、參數(shù)選擇(如PID參數(shù)選擇)等等,電路模型用一般的傳遞函數(shù)即可。仿真的結(jié)果在一定的程度上,為了解系統(tǒng)的工作情況提供幫助,有助于設計正確合理的系統(tǒng)。近年,隨著計算機技術(shù)和仿真技術(shù)的發(fā)展,已有一系列界面友好的仿真平臺出現(xiàn),其中,典型的有Spice、ICAP4.0-Interactive Circuit Analysis rogram和WE4.0-Electronics Workbench 等等,它們都具備器件庫、各種信號發(fā)生器,以及示波器、BODE圖顯示器等等,是典型的電子實驗臺,為電力電子系統(tǒng)的設計提供有力的輔助工具。中興ZXDU68 S601開關(guān)電源技術(shù)參數(shù)/報價目前不少的電源工作者對仿真軟件使用掌握不夠熟練,未能充分利用強大的CAD手段來進行分析和設計,導致在設計中走不必要的彎路,甚至有時候造成設計的失敗。此外,正版軟件價格昂貴也造成使用上一定困難的一個原因。在解析建模方面,目前流行的各種解析分析方法大多數(shù)是以R.D.Middlebrook等提出的狀態(tài)空間平均法(以占空比加權(quán)平均)為基礎的。狀態(tài)空間平均法是從變換器的不同拓撲的狀態(tài)空間方程出發(fā),經(jīng)過平均——小信號擾動——線性化處理,將一個非線性、時變、開關(guān)電路轉(zhuǎn)變?yōu)橐粋等效的線性、時不變、連續(xù)的電路,可以應用經(jīng)典控制理論的分析線性系統(tǒng)的方法,如拉氏變換、根軌跡圖和Bode圖等等,在頻域內(nèi)分析設計系統(tǒng)。可叫分析系統(tǒng)在平衡點附近的小信號擾動時近似的瞬態(tài)響應特性以及系統(tǒng)的穩(wěn)定性等等。? 狀態(tài)空間平均法簡單通用,為開關(guān)變換器提供了簡便和系統(tǒng)的分析工具,是簡明性和精確性的一個較好的折衷,也是大多數(shù)變換器分析方法的基礎。但是,它也有不少難以克服的缺點,如無法估計輸出紋波的大小,穩(wěn)定性分析不夠準確,難以對大信號過程作出中興ZXDU68 S601高頻開關(guān)電源機柜 分析,也不能分析軟開關(guān)變換器。
常規(guī)通信電源的設計,對PWM變換器的處理,實際是把它當作一個低頻的環(huán)節(jié),即是把經(jīng)過狀態(tài)空間平均以后所得的電路模型,簡單得出占空比(控制量)與輸出電壓(被控制量)傳遞函數(shù)關(guān)系。以及負載電流、輸入電壓等等擾動量對輸出電壓的傳遞函數(shù)關(guān)系,采用經(jīng)典控制理論的常規(guī)方法設計系統(tǒng),然后對其穩(wěn)定性等等性能指標進行校驗,沒有反映系統(tǒng)的高頻部分。倘若高頻的部分起主要作用,則所得的結(jié)果很良不準確,不幸的是穩(wěn)定性分析即屬此列。實際上,開關(guān)電源是一個非線性的系統(tǒng),系統(tǒng)存在著不同的過渡過程,即是由輸出電感和輸出電容等較大時間常數(shù)組成的毫秒級的暫態(tài)過程,以及功率器件在每個開關(guān)過程中,寄生分布參數(shù)起主要作用的,微秒級開關(guān)過渡過程。一般來說,即使是大信號分析方法,如果采用平均的方法的話,所得到的結(jié)果是反映時間常數(shù)大的過渡過程,而時間常數(shù)小的開關(guān)過渡過程很難反映出來,這是因為取平均是把高頻分量去掉了。雖然,近年提出的高頻網(wǎng)絡法把不同過渡過程的快變量和慢變量分無從理論上可以得出解析解,但由于解的復雜性,難以在工程中得到具體的應用。特別是近年來,軟開關(guān)技術(shù)出現(xiàn)以后,又導致狀態(tài)空間平均法難以進行分析。雖然近年出現(xiàn)很多分析方法,如諧波平衡法,等效電路法,采樣數(shù)據(jù)法,等效小參量法等等,但都顯得過分專業(yè)化,有的需要解復雜的微分方程,計算量過大;有的難以得到中興ZXDU68 S601開關(guān)電源技術(shù)參數(shù)/報價顯式解,有的解物理意義不明顯。此外,系統(tǒng)的開環(huán)和閉環(huán)的模型建立也需要一定的技巧。因此,必須繼續(xù)探討簡單、實用、具有明顯工程意義的電路模型和滿足工程需要的大信號分析方法。
四、電磁兼容性分析電磁兼容EMC(electromagnetic compatibility)是指在有限的空間、時間和頻譜資源下,各種設備可以一起正常工作而性能不會變差。對設備和系統(tǒng),要具有良好的電磁兼容性,就應既不受電磁環(huán)境的影響,又不給環(huán)境造成這種影響。電磁兼容性包括電磁干擾(EMI)和電磁敏感度(EMS)兩個方面,電磁干擾是設備和系統(tǒng)向外發(fā)出的干擾,電磁敏感度是設備對外來干擾的敏感程度和抵抗外界干擾的能力。電磁干擾叉有傳導干擾(通過導線或電源線向外傳送的干擾)和輻射干擾(通過空間電磁波向外的輻射干擾)。實際情況表明,電磁干擾會造成通信設備失效,通信噪音增大,計算機誤碼、信號誤差增大等等惡劣情況,直接影響通信的質(zhì)量和可靠性,隨著通信電源向高頻化和大功率化的發(fā)展,其電磁干擾發(fā)射的能量越來越大,其他電子設備、電力設備的廣泛應用,也使得通信電源的電磁環(huán)境越來越復雜,通信電源很容易構(gòu)成主要的干擾源和被干擾者,解決通信電源的電磁干擾和射頻干擾問題,對有效提高通信質(zhì)量和通信可靠性有極其重要的作用。目前許多電源工作者只著重于電路原理的正確性,對電磁兼容性問題缺乏足夠的認識,總是等到調(diào)試過程中才修補,往往造成電源系統(tǒng)的不能正常工作或不必要的浪費。電磁兼容性問題既有理論上的問題,但更多的是一種實驗技術(shù)和工藝技術(shù),需要從電磁干擾的產(chǎn)生、傳播以及接收等方面加以研究解決。此外,對電源本身來說,選擇合適的電路拓撲結(jié)構(gòu),合適的電路元器件,適當?shù)?/span>濾波器,良好的屏蔽措施,合理的布線和正確的接地方式和良好的防雷措施,在監(jiān)控系統(tǒng)設計中,充分考慮各種各樣抗干擾措施,都是解決以上問題的有效的方法。除了以上措施以外,軟開關(guān)技術(shù)和功率因數(shù)校正技術(shù)以及其它一些新技術(shù),也都為上述問題的解決提供一條新的途徑。中興ZXDU68 S601開關(guān)電源技術(shù)參數(shù)/報價五、結(jié)論通信電源的設計,既有理論問題,涉及到現(xiàn)代電力電子技術(shù)、微電子技術(shù)、自動控制理論、計算機技術(shù)、磁性材料等相關(guān)學科知識,因此,應用相關(guān)理論的最新成果到通信電源中,是提高其性能水平、質(zhì)量和可靠性的重要措施之一。除此之外,通信電源的設計,也是一種實驗技術(shù)和工藝技術(shù)。元器件的選擇,工藝技術(shù),電磁兼容性的考慮等等,也都是設計時要充分考慮和認識的。因此,在理論和實踐中不斷創(chuàng)新,對通信電源的更新?lián)Q代和培養(yǎng)高水平的開發(fā)隊伍具有重要的意義。

The
In recent years, with the progress of technology, especially the power devices upgrade, constantly using new electromagnetic material, continuous improvement of power conversion technology, progress control method, and related disciplines of technology integration, communication in power system reliability, stability, electromagnetic compatibility, to eliminate the harmonic and improve power could have made considerable progress in terms of utilization rate, reduce the loss, improve the dynamic performance of the system and so on. In addition, due to the wide application of computer monitoring system in communication power supply, but also makes the degree of intelligent power increasing, system maintenance and management capacity has been strengthened; and the perfect grounding system and lightning protection measures to further improve the power supply of the MTBF time average no fault. At present, the communication power is developing in the direction of high frequency, high power density, high power factor, high efficiency, high reliability and high intelligence. The
China's communication power has gone through a road of introduction of technology, joint venture production and independent development and development. Due to the good market prospect of communication power and the high added value of products, many domestic scientific research institutes and manufacturers have invested a lot of manpower and material resources to develop and develop a good communication power supply. At present, domestic manufacturers of communication power supply with independent intellectual property rights are: intercontinental communication power Refco Group Ltd in Wuhan, Shenzhen, HUAWEI,中興ZXDU68 S601開關(guān)電源技術(shù)參數(shù)/報價 ZTE, Beijing power company, Zhuhai electric power company Hangzhou gold, Qiao Xing company etc.. The main domestic joint venture manufacturers are: Shanghai xindianyuan communication power supply company, SIEMENS company in Shanghai, Shanghai in Guangzhou Pearl River Tektronix Inc - Vladimir, Telecom Equipment Manufacturing Co. Ltd. etc.. The main foreign communication power market saw the manufacturers: the United States, Liberty (Liebert), and Rita (Reltech) company, Norway Yida group company (Eltek), New Zealand's swichtec (Switchtech), etc.. After entering the 9O era, with the technological innovation and progress, the products of foreign telecom power suppliers usually have the following characteristics: (1) adopt current control mode instead of voltage control mode. (2) the phase shift control mode soft switching technology, the full bridge zero voltage switch, is used. (3) the power factor correction technique is used. (4) it has the function of module automatic flow sharing. (5) the function of four remote remote control, telemetry, telecontrol and remote control. (6) the management technology of battery monitoring and charging current limiting function. (7) the interface - friendly monitoring software. (8) good electromagnetic compatibility and lightning protection measures. (9) complete protection and alarm function. The
In terms of the overall performance, there is a gap between the level of China's telecommunication power supply and the foreign products of the same kind. The main gap is the reliability, stability and technical performance of the work. Therefore, organizational strength developed with independent intellectual property rights, a new generation of communication power supply with high technology content, to revitalize national industry, improve product quality and competitiveness, has an important significance to improve the level of research and development team, will also bring remarkable economic benefits and social benefits. In

The power of communication, the core part is the switch converter, and the converter technology progress is mainly embodied in the device, the circuit topology and control technology breakthrough, therefore, the latest achievements of the application of these technologies related to communication power, communication power is one of important measures to improve the technical performance, quality and reliability. Can be discussed from the following aspects: the
1, from the topological structure and device aspect of the circuit, the transformation circuit topology of communication power supply mainly adopts double single ended circuit, half bridge circuit and full bridge circuit. It is generally believed that it is appropriate to use double single end circuit or half bridge circuit in medium and small power situations, and full bridge conversion circuit is used in high-power situations. Although there are some new converter circuit topology, such as the CuK converter input, low output ripple, the transmission ratio of Buck-Flyback converter and so on, but the emergence of a series of new technology of soft switching technology, cooling circuit topology transformation, in the present case, the circuit topology changes little.

From the perspective of power devices, electronic devices from the half controlled device (SCR), to the development of the self turn off devices of all kinds, and has the power integrated circuit (PIC) 中興ZXDU68 S601高頻開關(guān)電源機柜 the emergence of the driving mode from the current driven development model of driving mode for voltage type. In the current communication power supply, due to the different applications, field-effect transistor (MOSFET) and insulated gate transistor (IGBT) are two kinds of devices that are used more. Generally speaking, FET drive is easy to drive, with high switching frequency, positive temperature coefficient and easy parallel connection. Its disadvantage is that its structure is limited, its voltage is not high, and its body resistance is too large (although parallel can reduce its resistance). It is generally believed that in field of medium and low power, FET is suitable, and its switching frequency is very high, which can reduce the volume, weight and cost of the entire power supply. Driving can use simple pulse transformer, and it can pass through the tube.
