Abstract

This paper presents a new method of injection of high voltage pulses (IHVP) during commutation in order to shorten current’s rising-edge time and reduce the torque ripple. A quantitative method for choosing the voltage magnitude and the pulse width is put forward with trapezoidal back EMF under square voltage wave condition. Its optimal discrete solutions and the principle of choosing the discrete pulse coefficient under PWM control are derived. Finally, the effect of the method is verified by experiments.
