Abstract
An isolated DC-DC converter with high gain is proposed for applications using low voltage renewable energy sources. Circuit consists of an impedance network at its first stage, then a push – pull converter and a voltage doubler rectifier circuit in the final stage. This topology combines inductive coupling in impedance source network and transformer turns ratio for high gain in addition to voltage doubler. The highlights of the proposed converter topology are high gain, reduced ripple in source current and galvanic isolation between source and load which is an important requirement in solar PV system. DC voltage gain derived for the converter proves its high gain ability. Simulation results found on MATLAB/Simulink are in compliance with the waveform obtained theoretically.
