摘　　要：介绍一种新型的直流调速方法。在车载动力系统中,往往需要使用低电压蓄电池来带动额定电压高的电动机。为了解决这个问题,在直流电动机的驱动中引入了库克电路,用它来调节电枢电压,从而获得宽的调速范围。该文用SABER仿真对升降压调速系统的可行性进行分析,并通过仿真来辅助设计双闭环调速系统的比例、积分参数,最后用实验对该系统进行验证。A new method of the DC PWM speed regulation system is introduced. In the vehicle power system, the low voltage of batteries is always transformed to drive a high voltage motor. In order to deal with this problem, cuk converter which can regulate the armature voltage in a wide span is applied in the PWM speed system. SABER simulation is used to prove the feasibility and to optimize PI parameters. In the last section, the correctness of the cuk PWM system is proved by experiment.
