DESIGN AND ANALYSIS OF AN INTERFACING CIRCUIT FOR SOLAR CELL SYSTEM WITH AC LOAD

This report represents a design for an interfacing circuit for solar cell system with AC load. The aim is to produce 240 VAC with 50Hz frequency to power up small AC equipment such as the power drill. This work has involved the design of two circuits, namely the booster with two charge pump circuit and the half bridge parallel bridge inverter that satisfy the requirements. The booster circuit amplifies the very low input voltage from the solar panel to a larger output voltage, while the half bridge PRC converts the DC outputs from the booster to the corresponding AC voltage. The circuits' shows to be a viable to function as an interfacing circuit for the solar panel and the AC load as intended. The output voltage from solar panel, typically 24 V is multiplied using a booster circuit before being converted into alternating current by an inverter circuit.
