摘要

三电平二极管钳位型桥式变流器是适应高电压、大功率应用环境比较好的方案。然而，三电平逆变器开关管在开通关断过程中普遍存在电压应力超标问题。为了解决上述问题，对三电平逆变器开关管应力进行分析后提出了开关管驱动保护电路，设计并优化了三电平的驱动波形。最后，在三电平逆变器实验平台上进行试验验证了该方法的有效性。

Abstract

Three-level diode-clamped bridge converter is a good solution for high voltage and high power applications. However

the problem of excessive voltage stress is common in the switching on and off process of three-level inverter switch transistor. In order to solve the above-mentioned problems

after analyzing the stress of three-level inverter switch tube

a switch tube drive protection circuit is proposed

and the three-level drive waveform is designed and optimized. Finally

the effectiveness of the proposed method is verified by experiments on a three-level inverter experimental platform.
