基于同步滤波重构法的双三相永磁同步电机单电流传感器相电流重构

In dual three-phase permanent magnet synchronous motor (DTP-PMSM) drive, six-phase current information is critical to motor control. However, the adoption of multiple current sensors increases the size and cost of inverters. To mitigate this issue, this article proposes a method to reconstruct six-phase currents of a DTP-PMSM by using a single current sensor (SCS). First, the SCS is repositioned t...
