在电压源逆变器中，可以使用耦合电感器将单元并联以增加额定功率和带宽。为了成功地实施这一策略，关键是要实现所有储能单元对输出电流的平衡贡献。还应控制环流并使其最小化，以防止开关器件中的额外损耗。本文提出了一种利用状态反馈控制器实现磁耦合电感逆变器单元间均流的有效方法。实验结果验证了所提出的平衡方法的性能。
Coupled inductors can be used to connect cells in parallel in a voltage source inverter to increase both rated power and bandwidth. To successfully implement this strategy it is critical to achieve a balanced contribution to the output current by all paralleled cells. Circulating currents should also be controlled and minimized to prevent additional losses in the switching devices. This paper presents an effective method to achieve current sharing between inverter cells paralleled via magnetically coupled inductors, using a state feedback controller. Experimental results are presented validating the performance of the proposed balancing method.
