摘要

IGBT死区时间的合理设置是零电压开关（ZVS）型LLC变换器实现软开关的必要条件。在IGBT关断时，由于其输出电容非恒定，导致死区时间设置相对复杂。文章分析了IGBT的关断特性，指出在LLC谐振电路中工作结温越高，工作功率越大，越不利于实现软开关；提出应在最高工作结温和最大工作负载情况下设计最小和最大死区时间。最后，通过搭建60 kW的LLC变换器进行验证，试验结果与理论计算结果基本一致，验证了优化设计的准确性。

Abstract

In ZVS-LLC resonant converter, proper dead time is essential for IGBT to realize zero-voltage-switching. In fact,the output capacitor of the IGBT is not constant when the IGBT is switching off, which makes the design of the dead-time relatively complicated. The switching characteristics of the IGBT was analyzed, indicating that in the LLC resonant circuit, the higher the working temperature and the heavier the load power were, the less conducive to realize the soft-switching of the IGBT. It was proposed that the minimum and maximum dead-time should be designed at the full load and the maximum working temperature condition. Finally, a 60 kW LLC converter was built to verify the correctness of the optimal design. The experiment results basically consistent with the theoretical calculation results.
