In order to eliminate the voltage oscillation caused by the reverse recovery of the rectifier diodes, a resonant inductance and two clamping diodes can be introduced to the primary side
為了消除輸出整流管的電壓尖峰,可以在原邊加入一個諧振電感和兩個箝位二極體。Then a thorough analysis to the bias - magnetic of ppfc is made. the retraining effects of the main parameters ( include clamping capacitance c, output filter inductor lf, load r, the leakage inductor ls and source winding resistance r ) are studied under the conditions of different von, different ton and different winding parameters. then a conclusion can be drew, that the smaller lf and the bigger r are, the better the bias - magnetic is restrained and c has a best value to retrain the bias - magnetic
分別對管壓降不同,導通時間不同以及兩原邊繞組參數不一致(包括漏感、電阻、激磁電感三種情況)的情況下,主要參數(包括箝位電容c 、輸出濾波電感lf 、負載r 、原邊繞組漏感ls 、原邊繞組電阻r )對偏磁的抑制作用進行了模擬分析研究,得出lf越小, r越大時激磁磁勢偏移量ni越小, c在其他參數確定時對抑制偏磁有最優值等結論,為參數的優化設計提供了依據。Because of the clamping capacitor and the interleaved structure, it has some good features compared with other flyback converters, such as : the topology is simple and can be realized easily ; the voltage spike of the power switch is availably restrained and without leakage - inductance energy loss ; the ripple of the input and output current is reduced, correspondingly, the volume and weight of the output and input filter is also significantly reduced
由於箝位電容的加入,相對于其他類型的反激式變換器電路,該拓撲具有一些獨特的優點:電路結構簡單且易於實現;無需另加輔助開關管,實現了開關管的有源箝位,抑制了開關管的電壓尖峰;提高了輸入、輸出電流的脈動頻率,減小了輸入及輸出濾波器體積。The following is the main works and conclusions of this thesis. the novel upfc needs high power rate because it is generally used in high voltage transmission lines. after studied high - power converters and the literatures of upfc, the main circuit topology of novel upfc base on diode - clamping multilevel inverter is presented and the principle of using novel upfc to eliminate zero sequence and negative sequence currents is analyzed
本文所做的主要工作及得出的主要結論如下:由於upfc一般用於高壓輸電線,其功率等級要求很高,在綜合研究大功率變換器和upfc現有文獻的基礎上,提出了基於二極體箝位多電平變換器的新型upfc的主電路拓撲,分析了用其來濾出高壓輸電線非全相運行時所產生的零序和負序電流的原理。1 ) the transformer leakage inductance will cause surge voltage across the switches. two clamp circuits are combined to solve this problem : lcd clamp circuit, in which the voltage across clamp capacitor is no reverse ; flyback clamp circuit, which consists of an additional flyback winding coupled with the boost inductor and a diode connected to the output terminal
本文綜合了兩種箝位電路: 1 ) lcd箝位電路,箝位電容上電壓不反向; 2 )通過增加一個與升壓電感耦合的反激線圈和一個連接到輸出電容的整流二極體,構成反激箝位電路。Double forward converter ( dfc ) has many advantages, such as inherent anti - break - though capability, auto clamping the switch voltage etc. regarding the excellent reliability, dfc is one the most widely used topology in the industrial applications, especially for low output voltage area, such as telecommunication energy systems and welding power supply
雙管正激變換器具有內在抗橋臂直通的優點,能使開關管上的電壓自動箝位在輸入電源電壓。由於其可靠性高,電路設計簡單,因而成為目前在工業中應用最普遍的變換器結構之? ,特別是適合於輸出電壓較低應用場合,比如通信系統中的一次電源和弧焊電源。The converter not only keeps all the characteristics of the basic zvs pwm h - fb tl converter, but also eliminates the voltage oscillation and voltage spike across the rectifier diodes in both three - level mode and two - level mode, leading to a reduced voltage stress of the rectifier diodes
本文在基本zvspwmh - fbtl變換器中引入兩只箝位二極體,無論是在三電平模式還是在兩電平模式,都可以消除輸出整流二極體反向恢復造成的電壓尖峰和振蕩,降低了輸出整流管的電壓應力。To reduce the emi, reverse reset of the diode are studied, and design way about spike - killers and saturable inductors witch can suppress voltage and current spikes are showed. in this thesis, a transformer clamping full - bridge dc / dc converter is presented to salve the high input voltage. in this chapter, the operating principle is analyzed and experimental results have been showed on the 2kw converter
在處理高壓問題上,本文又提出了變壓器箝位高壓大功率dc dc全橋變換器拓撲方案,文中對其工作原理進行了分析,文中以一臺2kw的原理樣機對其工作原理進行了驗證,很好地解決了輸入電壓高的問題。A novel single phase three - level inverter is proposed, which is named hybrid three level inverter. a leg of neutral - point clamped inverter takes place of one of the two legs of the conventional full - bridge inverter. the great advantage is the harmonics of the output voltage is reduced a lot, so the size of the output filter can be reduced greatly
本文提出一種單相復合式全橋三電平逆變器,它是將傳統全橋逆變器的一個橋臂換為中點箝位三電平橋臂,這樣逆變器可以輸出三電平的電壓波形,其諧波含量被大大減小,因此輸出濾波器的大小可以減小。分享友人
