Maintain Maximum Power Point Tracking of Photovoltaic using SEPIC Converter

Abstract

this article acquaint the layout of a Single Ended Primary Inductance Converter (SEPIC) DC-DC converter for optimum photovoltaic (PV) power. The DC-DC SEPIC converter allows the DC power range to be set to maintain a similar power output. This article highlighted the improvement of SEPIC converters over other dc-dc converters. In this article, Output of solar PV system is control by the SEPIC DC-DC converter. SEPIC Converter is digitally controlled by microcontroller LPC2148. Output of SEPIC, convert into Alternate Current (AC) using microcontroller based control inverter. The proposed work was designed and implemented using the Proteus 8 and the resulting results were presented and validated.
