Abstract

Abstract: This paper introduces a pulse‐width modulation (PWM) method for a two‐motor drive system that reduces the propagation of conduction noise to the power supply. This two‐motor drive system consists of two motors with two inverters, each of which is connected to a common DC bus. The proposed method suppresses the common mode voltage ideally to zero by shifting the rise and fall times of the output voltage of each inverter. Our experimental results show that the rise and fall times of the output voltage can be synchronized even when the two inverters are driven at different amplitudes and frequencies. We confirm that the proposed method suppresses the propagation of conduction noise to the power supply.
