Abstract

本实用新型涉及直流电压自平衡软开关三电平逆变器,属于电气工程中的变流技术领域,目的是为需要使用三电平逆变器的高压、大容量应用,提供一种同时有软开关和直流电压自平衡能力的三电平逆变器,以减小开关损耗,简化控制电路。为了实现以上目的,本实用新型在现有的含准谐振软开关电路的三电平逆变器其中一个桥臂上,由电压自平衡电路取代篏位二极管,其中电压自平衡电路由两个开关元件,并联一个电容加电感的串联支路组成。本实用新型有益效果在于:不需要额外的直流电压控制算法,简化了控制电路,同时不影响软开关的效果。该技术方案同时适用于单相、三相或多桥臂的三电平逆变器,也同时适用于三相三线和三相四线的电力系统。
