Abstract

In order to reduce the noise and vibration of FPMSM produced by PWM, a hybrid random SVPWM (HR-SVPWM) method based on enhance NFV-SVPWM with full modulation ratio of Five phase voltage source inverter is proposed in this paper. The enhance NFV-SVPWM can solve the limitation of traditional NFV-SVPWM. The proposed HR-SVPWM is combined with RZ-SVPWM and RP-SVPWM. And an easy implementation method is proposed based on its principle. The voltage harmonics modulated by HR-SVPWM can be suppressed and balanced effectively. The correctness of HR-SVPWM and the suppression of high frequency voltage spectrum are verified by simulation. Finally, the correctness and effectiveness of current suppression are also verified by experiment on five phase permanent magnet synchronous motor.
