针对传统中高压变频器输入端带有体积庞大且价格昂贵的工频移相变压器问题，提出一种用于开绕组电机的新型单向能流矿用变频器拓扑。整流级采用3个单相二极管整流器+Boost变换器电路结构，输入侧无需工频变压器进行隔离，具有高输入功率因数、低输入电流谐波及低开关管电压应力等特点；逆变级采用开绕组连接方式与交流电机相连，实现了相间隔离。在该拓扑基础上，进一步研究了一种低共模电压的空间矢量脉宽调制SVPWM（space vector pulse width modulation）策略，实现了系统单位功率因数运行、共模电压抑制及开绕组电机零序电压的消除。

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.
