摘　　要：A family of switched-capacitor based resonant converters is present.All converters are in step-downmode.By adding different number of switched-capacitor cells,different output voltage conversion ratio can beobtained.All switching devices in the converters operate under zero-current switching.Both high frequencyoperations and high efficiency are possible.A family of switched-capacitor based resonant converters is present.All converters are in step-down mode.By adding different number of switched-capacitor cells,different output voltage conversion ratio can be obtained.All switching devices in the converters operate under zero-current switching.Both high frequency operations and high efficiency are possible.
