Abstract :
A new Hybrid Boosting Converter(HBC) is proposed in this paper. It combines the advantages of regulation capability of traditional inductor based DC-DC converters and gain boosting ability of switched capacitor converters. It is capable of boosting the input voltage to ten times with single active switch and one inductor while maintaining high efficiency. In addition, the switch stress is low and output voltage has a wide regulation range. A modeling method for the proposed converter is presented in this paper. The PWM regulation capability is confirmed by theory and experiment. A 200W, 35V to 380V HBC prototype was built that demonstrated a peak efficiency of 95.44% using normal electrolytic capacitors.
