Abstract
this paper studies a PWM control strategy suitable for SiC traction inverter aiming at good running performance of traction motor in full speed range, which combines the asynchronous PWM control and the optimal synchronous PWM control pursuing current harmonic minimum. The comparative study between the proposed strategy and the conventional strategy is conducted by experimental tests in terms of motor current quality, motor loss reduction, motor temperature rise and running noise suppression. The related experimental results have been detailed in this paper, which also confirm the validation of the proposed PWM control strategy.
