Design and Implementation Soft-switching MPPT SEPIC Converter Using P&O Algorithm

Abstract

This paper presents details of design and implementation of Maximum Power Point Tracking (MPPT) SEPIC Converter to maximize Photovoltaic (PV) power output. Perturb and observe (P & O) algorithm has been used as a tracking technique to determine MPPT. This algorithm are simple and efficient to determine the maximum power point (MPP). The soft-switching method will be added to the implementation of MPPT SEPIC Converter to reduce switching losses. The results show that the proposed MPPT method implementation can increase the output power of PV.
