摘要：
In this study, we propose a novel pulse-width modulation (PWM) method to reduces common-mode noise. The proposed method includes a 120-degree dormant two-phase modulated three-phase inverter that the comparative carrier of one of the two modulation phases. This configuration is easy to implement because it uses a triangular-wave carrier comparison. In an experiment using a three-phase inverter, the common-mode current was reduced by approximately 60%, and in particular, the carrier frequency component was reduced to approximately 1/10 that of the conventional sine-wave comparison PWM. © 2021 The Institute of Electrical Engineers of Japan.
