Abstract
Variable switching frequency PWM (VSFPWM) control has been adopted in the induction motor drive in recent work. Due to the position-related phase inductance, interior permanent magnet synchronous motors (IPMSM) have the difficulty to adopt VSFPWM. In contrast to using thevenin theory from previous work, this paper applies d-q transformation to IPMSM drives to predict the phase-current ripple and applies VSFPWM to control the current ripple of IPMSM. Simulation results validated the effectiveness of the theoretical analysis.
