Abstract :
This paper proposes a new soft-switching strategy for three-phase inverter and rectifier applications. All the main switches and auxiliary switches are turned on and turned off under zero-current-transition (ZCT) conditions. Compared to existing ZCT techniques, the diode reverse recovery is reduced. In addition, the current stresses the auxiliary switches is reduced and evenly distributed. The operational principle and design aspects are described. Results of modeling of this scheme working in a mode of the rectifier are presented.
