一种用于自励同步电机零低速下的高频电压谐波励磁策略

Self-excited synchronous motor (SESM) can achieve brushless excitation by capturing energy from excitation winding. However, it is difficult to operate smoothly at zero and low speed. To address this issue, a novel excitation strategy based on high frequency voltage is proposed for SESM in this paper. First, the topology and excitation principle of SESM are introduced. On this basis, the relations...
