Abstract :
In this paper, based on generalized zero vector a novel simple PWM control circuit for a three-phase inverter is presented. The proposed control circuit, consists of a simple analog circuit to achieve function of DPWM (Discontinuous Pulse Width Modulation), has several advantages such as lower switching losses, higher efficiency and voltage usage utility, pure sinusoidal output and cost down etc. In practical, based on conventional SPWM the proposed control circuit, without complicated calculation, can generate the modulation signals of DPWM to drive an inverter with high efficiency. Finally, some experimental results are presented for verification.
