High Gain Quadratic Boost-Cuk Converter Based on Switched Capacitor for Fuel Cell Vehicle

Due to limited resources and global warming conditions, there is a paradigm shift in transportation from petrochemical to electric vehicles. Fuel cell vehicles are the emerging source of electric vehicles. Still, a wide range of voltage gain is required for the Fuel cell electric vehicles, which are satisfied by high-gain DC-DC converters to sustain the DC-link voltage from low-voltage fuel cell stacks. This study proposed a non-isolated DC-DC converter suitable for such applications to provide high gain for fuel cell electric vehicles. The proposed converters offer large step-up voltage by utilizing a single ground-referenced active power switch by combining the key features of switched capacitors, quadratic Boost, and Cuk converters. Compared to a conventional boost converter, the proposed converter reduces the voltage stress across the active power switch and can be used for high-power applications. The proposed converter is designed and driven, and its simulations are proofread and verified in MATLAB atmosphere.
