Abstract

A novel maximum power point tracking (MPPT) converter topology, based on the parallel power conversion technique (PPCT), to enhance the energy conversion efficiency in photovoltaic (PV) systems is analyzed. Extensive experimental verification of the operation of this converter topology, compared to other topologies, is included. Based on these results, the MPPT topologies are evaluated against each other for utilization in PV systems. The PPCT topology has the highest efficiency compared to the other power converters on the same basis. This increased efficiency is experimentally evaluated and analytically described. It is shown experimentally that the PPCT results in a meaningful enhancement of the basic converter efficiency, from 76% to 94% with a 12 V battery and from 85% to 95% with a 36 V battery
