Abstract

The low voltage DC source such as PV/Battery/Fuel-Cell/Ultra-Capacitor system requires high voltage gain DC-DC converter for integrating it with the high voltage load side such as hybrid electric vehicle (HEV). A single switched impedance network (SSIN) is reported most recently to reduce the inductor current stress but the stress across the other components can be further reduced. In this paper, an improved DC-DC converters is reported by adding the additional switched capacitor structure to minimize the voltage stress. The operating characteristics, steady-state analysis and comparative analysis with SSIN are discussed. The proposed converter is operated for 325 W output power rating and tested for providing twelve times voltage gain. The efficiency of the proposed converter is also reported for different output power ratings which are in the range 91.5%-93.41%.
