Abstract

A converter without DC Link components needs snubber circuits, in order to assure the path of the load current during the dead-time period of the PWM rectifier section. In the snubber circuits, losses have been dissipated every time the switches of the rectifier section are turned on and turned off. During the zero voltage vector period of the inverter section, the load current does not flow in the PWM rectifier section. So if each switching operations of the PWM rectifier section are done in the zero voltage vector period, it is not necessary to assure the path of the load current. Therefore, snubber circuits are not necessary in the PWM rectifier section. In this paper, we describe a zero current switching strategy of the PWM rectifier section during zero voltage vector periods of the inverter section. The proposed strategy is verified by computer simulation and experimental test on an induction motor drive.
