Abstract
This paper introduces selective harmonic elimination PWM (SHEPWM) technology applied in PMSMs. According to model of PMSMs, relation between harmonic currents and voltages is derived. From this relation, selection principle of SHEPWM is different for salient pole PMSMs and non-salient pole PMSMs. Besides, the method of smooth transition between different SHEPWMs is introduced. Simulations and experiments have been completed to test those conclusions correctness.
