This paper proposes a PWM converter with dissipative structure.Effective rapid disposal of motor braking using resistors is realized to avoid loading failure caused by the rising voltage of capacitance.Based on an analysis of the process of two loading modes,the paper discusses the control on the load of torque by current command in different loading modes.Simulation results prove the feasibility of the converter structure for fast torque tracking.

Key words: PWM motor driver;torque control;loading system
