通过多同步参考系电流谐波重分配抑制内置式永磁同步电机转矩脉动的同步优化PWM方法

Torque ripple suppression plays a crucial role in the electric drive systems of electric vehicles. This article proposes a torque ripple suppression method for interior permanent magnet synchronous machine drive systems based on synchronous optimal pulsewidth modulation (SOPWM). First, the relationship between current harmonics vectors and switching angles of SOPWM is derived in a multisynchronous...
