The iik absolute maximum rating specifies the maximum current that may be put through the ground - clamp diode 輸入箝位電流iik規(guī)定了流過(guò)接地箝位二極管的最大電流的絕對(duì)最大額定值。
You may exceed the negative input - voltage rating if you ensure that you are not putting too much current through the ground - clamp diode 同樣) ,如果你能保證不太大電流通過(guò)地電位箝位二極管,則一樣可以超過(guò)負(fù)輸入電壓值。
This thesis focuses on the development of the dc / dc stage , which adopted the phase - shifted zero - voltage - switching ( zvs ) pwm full - bridge converter with two clamping diodes 本文主要研究單相靜止變流器的dc / dc級(jí),它采用加箝位二極管的移相控制zvspwm全橋直流變換器。

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管,無(wú)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管反向恢復(fù)造成的電壓尖峰和振蕩,降低了輸出整流管的電壓應(yīng)力。
The clamping diodes conduct only once in a switching period , and the resonant inductance current is smaller in zero state , leading to a higher efficiency and reduced duty cycle loss . the operation principle of the improved converter and the comparison with the original converter are analyzed in this paper . the effect of the blocking capacitor in series with the transformer or resonant inductance is discussed , and a best scheme is determined 本文將諧振電感和變壓器交換位置,使變壓器與滯后橋臂相連,這樣箝位二極管在一個(gè)開(kāi)關(guān)周期中只導(dǎo)通一次,同時(shí)零狀態(tài)時(shí)諧振電感電流較小,有利于提高變換效率和減小占空比丟失,本文分析改進(jìn)后變換器的工作原理,并與改進(jìn)前的變換器進(jìn)行對(duì)比,討論隔直電容在不同位置對(duì)變換器工作的影響,確定一種最佳工程方案。
