| Abstract: | According to torque pulsation of brushless DC machine, a new current regulation PWM (CRPWM) method by raising voltage of commutation was proposed in this paper. An improved hardware circuit was designed, and simulation results were compared between conditional and improved circuits. Simulation results demonstrated that current waves were improved and torque pulsation was reduced by the proposed method. |
