Abstract

A series LC resonance-pulse assisted current-fed three-phase converter has been proposed and investigated in this article. The aim is to present a simple and practical high boost topology that achieves zero current switching (ZCS) of the semiconductor devices and regulates the output voltage for wide source voltage and load variations. Resonance characteristics were exploited during short switching overlap time to cause natural commutation of the active devices eliminating turn-off voltage spike along with reduced circulating currents in the converter. Current-sharing three inductor methodology has been employed resulting into reduced current stresses on the primary side semiconductor devices and reduced heat sink requirements. In addition, the gate driving and control requirements are simpler due to devices having common ground with the supply thereby improving the overall conversion efficiency. Output voltage is regulated by employing variable frequency control. The proposed converter analysis and design are validated using simulation results from PSIM 11.01 Software.

部分串联谐振脉冲辅助零电流开关电流馈电三相共流DC-DC变换器

本文提出并研究了一种串联LC谐振脉冲辅助电流馈电三相变换器。目的是提出一个简单实用的高升压拓扑，实现半导体器件的零电流开关(ZCS)，并调节宽源电压和负载变化的输出电压。在短的开关重叠时间内，利用谐振特性导致有源器件的自然换相，消除了关断电压尖峰，同时降低了变换器中的循环电流。采用电流共享三电感方法，减少了初级侧半导体器件上的电流应力，降低了散热器要求。此外，由于器件与电源具有共地，因此栅极驱动和控制要求更简单，从而提高了整体转换效率。输出电压由变频控制调节。利用PSIM 11.01软件的仿真结果验证了所提出的转换器分析和设计。
