Abstract :
This paper presents a new single carrier wave comparison PWM method for 3 level 3 phase Vienna type rectifier. The theoretical background for the single carrier wave comparison PWM is presented. The model for this Vienna rectifier is reviewed briefly and the voltage unbalance problem according to the offset duty is analyzed. Finally, the simulation and experimental results prove the effectiveness of the analysis results.
