摘要： The switching rectifier and switching inverter on a motor drive unit are modulated to indirectly change the magnitude of current and voltage stored in DC link by controlling the magnetic field of the motor to correct for both power factor lead and power factor lag over a wide range of motor speeds and conditions while maintaining a predetermined motor operating point.
摘要翻译： 电动机驱动单元上的开关整流器和开关变换器被调制以通过控制电动机的磁场来间接地改变存储在直流母线中的电流和电压的大小，从而在宽范围内校正功率因数导通和功率因数滞后 同时保持预定的电动机工作点。

摘要： A non-isolated multiport DC/DC converter topology is provided. The non-isolated multiport DC/DC converter topology is modular and can incorporate an unlimited number of independent input or output ports. The efficiency of the non-isolated multiport DC/DC converter topology is improved through partial power processing techniques without having isolation in the converter. The non-isolated multiport DC/DC converter topology also provides a balanced DC neutral point, making it an ideal candidate for bipolar DC grid or as the front-end of a multilevel DC/AC converter.
