一种用于双三相永磁同步电机的新型四桥臂逆变器拓扑

This article proposes a novel four-leg inverter topology to drive the dual three-phase permanent magnet synchronous motor (DTP-PMSM) with 180° phase shifting. Without access to the midpoint of dc bus capacitors, the proposed four-leg inverter can not only drive the DTP-PMSM with the same torque capability as the conventional six-leg inverter but also avoid the voltage fluctuations of the capacitor...
