Abstract

This paper proposes a DC-DC power converter topology based on a modified Flyback Converter (FC). The aim of the proposed topology is to increase the voltage gain by connecting the inputs of N isolated FCs in parallel and the N secondary inductances in series. This scheme reduces the current in each switch then reducing the associated losses. A single diode and an output capacitance complete the power converter circuit. A Proportional+Integral (PI) controller is used to control the output voltage with the converter operating in discontinuous current mode. The proposed converter can handle more power than the standard FC with a low number of active power devices. The system is modeled using PSIM platform and experimental results are presented considering a 1kW prototype.
