基于单电流传感器的五桥臂逆变器驱动双永磁同步电机无传感器控制方法

The five-leg voltage source inverter (FL-VSI) has been widely studied as a better fault-tolerant scheme. In this article, combined with the duty cycle correction method, a low-speed sensorless control method for dual permanent magnet synchronous motors driven by FL-VSI with single current sensor is proposed. A high-frequency (HF) voltage injection method is used to solve the dead zone of current r...
