摘要: Resonant switched capacitor (RSC) converter has the advantage of zero-current switching, however, its output power range is narrow and voltage conversion ration predetermined by topology. In this paper, a new duty ratio control method for RSC was presented. proposed method, discharging time fixed charging variable. By adjusting time, good regulation large changes in input and/or load values could be obtained. Most switching devices were still switching. The low current EMI kept scheme. A step-down used as an example paper. circuit operation principle steady-state characteristics described detail. prototype with been implemented tested; theoretical prediction verified experimentally
