Analysis of Solar Cells Battery Charger with DC-DC Isolated Forward Resonant Reset Converter with Large Signal Technique for Linear Controller Design

This paper analyzes mathematical model, using an averaged large signal model method of solar cells battery charger with dc-dc isolated forward resonant reset converter which can be charged by constant current and voltage. Magnetic field deflecting method with leakage inductance and resonant capacitor was applied to analyze this model. To control converter, PI control with concentrates on cut-off frequency technique was used to maintain 14.4 Vdc of constant output voltage and 29 W of output power at the maximum full load. Confirmed by the simulation results there is a consistency between the analysis result and the calculation result.
