N2 - The floating double boost converter (FBC), including two single boost converters, is a solution for fuel-cell and renewable energy applications. To reduce the inductor currents in the FBC converter, the interleaved boost converters (IBC) are used instead of single boost converters so that the four-phase floating interleaved boost converter (4P-FBC) is formed. However, it is well known that the IBC suffers a significant problem with the unbalanced inductor currents issue, leading to high input current ripple. This paper proposed a floating double series-capacitor boost (FSCB) converter to solve the problem. Moreover, the voltage gain is improved by more than double, and the input current ripple can be minimized. As a result, the proposed converter is suitable for new energy sources, such as fuel-cell and photovoltaic. A 1.6 kW prototype was built and tested to verify the performance of the proposed converter.
