In this paper, a high voltage gain bidirectional DC-DC converter for the Electrical Vehicle (EV) application is proposed. The converter provides the merits of both switched-inductor and switched-capacitor converters. The proposed converter has a wide voltage gain range, low voltage stress on the power semiconductor devices, and a common ground between the grounds of the input and output side. Besides, synchronous rectification is adopted to obtain zero voltage switching (ZVS) during turn on and turn off dead time and thereby, efficiency of the converter is increased. The operating principle of the converter is provided in both step up and step-down mode and then, voltage gains of the converter are derived for two modes. Finally, a 96W converter with a constant high-voltage side (240V) and low-voltage side (18∼24V) has been built to demonstrate the experimental validation of our proposed design. read more
