In this paper, the phase-shifted pulse width modulation (PWM) method is proposed in an asymmetric three-level neutral point diode clamped (NPC) converter for switched reluctance motor (SRM) drive. In order to control this converter, the level-shifted PWM method is used usually. The proposed modulation method is compared with the level-shifted PWM method on the basis of switching frequency and current ripple. The switching frequency is independent of the load in the proposed method, while current ripple in two cases is almost equal. The switching frequency changes in a nonlinear manner by changing the load in the level-shifted PWM method. Therefore, the switches stress will be increased by the load variation. The effectiveness of the proposed method is verified by theoretical, simulation and comparison results.
