摘　　要：在多变换器电力电子系统中,负载变换器可以等效为前级变换器的恒定功率负载CPL(constant power load),这给系统带来了等效负电阻,导致系统不稳定,而采用主动阻尼的方法能够解决这个问题,并且不产生额外功耗,故根据主动阻尼方法改进了Buck DC/DC开关变换器。In muhi-converter electronic power systems, load converters could be equivalent to constant power load （CPL） of the front- end converter, thereby the equivalent negative resistance was brought, which destabilized the system. In this paper, the implementation of novel active-damping techniques can overcome the problem, and it wouldn＇ t consume extra problem. The proposed active-damping method was used on modifying Buck DC/DC converters.
