摘要

对零电压开关(ZVS)中半导体功率开关(阀)串联的基本理论进行了分析。分析了开关器件参数在稳态和暂态状态下对开关电压分布的影响。结果表明，采用零电压vs技术时，电压均衡元件的设计要比采用硬开关时容易。仿真结果验证了分析和设计方法的正确性。这项工作对于大功率软开关阀和转换器的设计是非常重要的。

Series connection of power switches for very high power applications and zero voltage switching

The basic theoretical analysis for series connection of semiconductor power switches (valve) for zero voltage switching (ZVS) is presented. The influence of the switching devices parameters on the switches voltage distribution during steady- and transient-state conditions are analyzed. It is shown that when ZVS technique is used the design of the voltage equalization elements is easier than when hard switching is used. Simulated results are presented to validate the analysis and design methodology. This work is supposed to be important for very high-power soft-switching valves and converter designs.
