基于电容耦合有源阻尼的LCL型高速永磁同步电机单电流反馈谐振抑制方法

This article proposes a single-motor-current feedback resonance suppression method for LCL-equipped high-speed permanent-magnet synchronous motor drives based on capacitively coupled active damper. The proposed method does not require any additional sensors or high-bandwidth current controllers, and an adaptive controller is designed to dynamically adjust the feedback gain. Compared with the activ...
