In this paper, a new interleaved switched-capacitor bidirectional DC-DC converter with a high step-up/step-down voltage gainis proposed. In this converter, two inductors, four capacitors and four semiconductors are used. The voltage gain of theproposed converter is higher than conventional converters such as buck-boost, boost, Cuk and is compared with some newconverters. In order to reduce the ripple of the current through the low-voltage side, an interleaved structure is adopted in thelow-voltage side of this converter. Furthermore, the equations of the voltage, the voltage stress for switches and currents arepresented in different modes. To verify the operation of the proposed converter, the experimental results are provided.
