Abstract: The permanent magnet synchronous motor (PMSM) has many advantages, such as high energy density, high efficiency and high power factor, and its application field is rapidly expanding. The traditional main circuit structure of three-phase three-leg topology with the space-voltage vector pulse width modulation (SVPWM) technology can reduce the winding harmonic currents and meanwhile improve the utilization rate of the DC voltage, thus reduce the torque ripple of the motor and broaden the speed range of motor eff…
