Aiming at eliminating the bulky and expensive line-frequency phase-shifting transformer at the input of the traditional medium/high voltage converter for AC motor drives, a new unidirectional power flow mining converter topology for open-end winding motors is proposed. The rectifier stage of the proposed converter topology adopts three single-phase diode rectifiers + Boost converter circuit structure without line-frequency transformer isolation, which is characterized by high input power factor, low input current harmonics and low switching device voltage stress. The inverter stage is connected to the AC motor by adopting stator open-winding connection for the isolation between phases. On the basis of the proposed topology, further investigates a low common-mode voltage space vector pulse width modulation (SVPWM) strategy, which achieves unity power factor operation of the system, the suppression of the common mode voltage in the rectifier stage, and the elimination of the zero sequence voltage in the open winding motor.
