N2 - The Cuk dual resonance core (DRC) realizes overlapping dual resonance to regulate its output voltage. In this paper, a Cuk DRC-based Dickson Resonant Switched-capacitor Converter (DDRSC) was proposed. With on-time fixed frequency modulation, all transistors are turned on with ZCS operation and all diodes are turned off with ZCS operation, reducing the switching loss significantly. Most importantly, the conversion ratio of the Cuk DDRSC can be regulated continuously, widely and efficiently even at light load condition, which is a huge advantage over the traditional Dickson switched-capacitor converter (SCC) with limited control headroom. A 150W prototype was built to verify the converter operation principle and regulation capability.
