Abstract

This paper proposes a modified DC-DC flyback converter with high efficiency. The converter is based on an N-stages flyback converter with the inputs in parallel and output in series. A high efficiency is obtained by including an active snubber circuit, which returns the energy stored in the transformer leakage inductance to the input source. This topology reduces the current in each switch therefore decreasing conduction and switching losses. A single diode and an output capacitance reduce the passive elements and allow an economical implementation. The converter operates in discontinuous current mode (DCM) for facilitating the control of the system and handling more power than the standard flyback converter. The system is modeled using PSim v11 platform and simulation results are presented and discussed.
