Abstract

A 3-Phase 3-Level DC-DC Converter is used for high electric applications. In this paper, all power semiconductor switches are operated under Soft-Switching conditions. The outer-switches are operated within ZVS conditions by using charge transfer through flying capacitors, while the innerswitches are operated within ZVZCS conditions by using leakage inductances and blocking capacitors. Also, this paper describes the operation modes under ZVS and ZCS conditions. In addition, the simulation and experimental results are compared. The practical test is at 5.5 kW rated power and efficiency of 93.40%.

采用移相PWM策略的新型三相三电平ZVZCS DC-DC变换器

三相3电平DC-DC变换器用于高电应用。在本文中，所有功率半导体开关都是在软开关条件下工作的。外开关通过飞行电容器的电荷转移在ZVS条件下工作，而内开关通过泄漏电感和阻塞电容器在ZVZCS条件下工作。并介绍了ZVS和ZCS工况下的运行方式。并对仿真结果与实验结果进行了比较。实际试验功率为5.5 kW，效率为93.40%。
