Pulse-Width-Control Method of Voltage-Source 3-Phase Inverter to Reduce Common-Mode Voltage

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