Abstract

This paper proposes a control method for a three-phase PWM rectifier using only a single current sensor in the DC link. A PWM modulation strategy for reconstructing three phase currents from the DC link current is given. The states of the rectifier switch are modified so that all phase currents can be reconstructed in a switching period although active vectors are applied only for a short time. Therefore, a novel current control using an adjustment scheme of the modulation signal for a three-phase PWM rectifier is discussed, and verified with the experimental results
