High Gain Converter Design and Implementation for Electric Vehicles

In this paper, a new Single Ended Primary Inductance Converter based dc- dc converter operate in boost converter mode is proposed. The converter is designed by incorporating the quasi-Z source structure and switched capacitor cell. The salient features of the proposed converter are high range of voltage gain, less voltage stress across the semiconductor devices and high efficiency. This characteristic creates the high gain converter an exceptional interface among the dc source and the load inside the electric vehicle. The steady state analysis of this topology in continual operating mode and the transient behavior are analyzed. Finally, a prototype of the converter 100W/200V is fabricated to confirm the practicability with conceptual analysis of the high gain converter.
