| Abstract |
The paper presents a space vector based modulation technique able to reduce Common Mode Currents (CMC) in six phase integrated AC motor drives. The proposed modulation strategy performs a suitable selection of the inverter states in order to achieve a considerable reduction of the Common Mode Voltage (CMV) variations, with a slightly reduction of the DC bus utilization compared to the standard Space Vector Modulation (SVM) approaches; drives operating with the proposed modulation method still maintain same performance in terms of dynamic control.The entire analysis has been performed on a six phase motor configurations, supplied by a single two level multiphase inverter and the effectiveness of the theoretical study has been verified by simulation results. |
