【Abstract】 With the microscopic view of pulse width modulation (PWM) drive and the macroscopic view of motor control system, the analytical deduction and numerical simulation on regenerative braking of permanent magnet motor system fed by battery is presented. Research shows that the regenerating characteristics in PWM drive mode are determined by PWM modulation ratio, and different control methods have distinct braking and regenerating characteristics. The results have been adopted in electric vehicle engineering practice.更多还原
