Abstract
The paper gives in-depth analysis of the maximum utilization of DC power supply for variable-frequency PMSM in order to seek for higher utilization of electric energy. The maximum utilization was computed aiming at three PWM modes named SPWM, SPWM with 3rd harmonic injection and SVPWM, and the impact of PWM dead time on the maximum utilization was also analyzed. Based on the theoretical analysis, simulation and experiments were completed to verify the validity of this computation and analysis method. The conclusions provide the gist for engineering design of variable-frequency PMSM system.
