三相两电平电压源逆变器中电容与电感安全连接的软开关系统

This article presents a new soft-switching system for three-phase two-level voltage source inverters. In this system, capacitors are not connected in parallel to the main transistors, and inductors are not connected in series with the auxiliary transistors. Avoiding these types of connections protects the inverter transistors against damage in cases of disturbances in the inverter control system. ...
