Abstract

In this manuscript, to increase the conversion efficiency of high current low voltage bidirectional DC/DC converter is proposed. The proposed converter uses switched inductor and switched coupled mutual inductance in the proposed system. Here, the switched inductor is an impedance network consists of split inductors and switches, which provides the high voltage conversion ratio and improves the output power quality that need for the low voltage applications. It also used as a filter to circulate the high frequency switching harmonics. In the proposed circuit, leakage current and power loss of mutual inductance is decreased because of soft switching. Thus the proposed method helps to reduce the switching loss, possibly low electro magnetic interference (EMI) and easier thermal management. This is used in the development of light-load competence of power conversion of DC/DC converter. The proposed work performed using MATLAB/Simulink platform. Finally, the conversion efficiency of proposed high current low voltage DC/DC converter is compared with classical circuit.
