| 摘 要： | 由于电流源型半桥变换器(Current-Fed Half-Bridge Converter,简称CFHB)中存在变压器漏感,引起了开关管关断电压尖峰.为解决这一问题,提出了一种新的零电流开关脉宽调制(Zero Current Switching Pulse Width Modulationh,简称ZCS PWM)CFHB变换器,以有效地消除主功率管的电压尖峰.详细分析了这种新型变换器的工作原理和特性,并在一个28V输入270V输出的600W原理样机上进行验证,最后给出试验结果.

| Abstract: | The Current-Fed Half-Bridge(CFHB) converter suffer from the leakage inductance which results in oscillation and voltage spike.In order to solve this problem,this paper proposes a novel Zero-Current-Switching Pulse Width Modulation(ZCS PWM) CFHB converter,which can eliminate the voltage spike.The operation principle and characteristics of the novel converter are analyzed and verified by a prototype converter.The experimental results are also included in this paper. |
