Abstract:To increase the power factor and restrain the harmonic pollution,PWM rectifier is widely used in drive system.
The fixed switch frequency control strategy of the PWM rectifier has two main methods,SPWM and of the
strategy’s modes are established with the tool of Matlab,the results show that both the robust and the dynamic perfor-
mance of the system are upgraded under the SVPWM control strategy,and the power factor is also increased than SPWM.
Aiming at the weaknesses that the SPWM control method are lower voltage utilization and more ha
