High Efficiency Non-isolated Three Port DC-DC Converter for PV-Battery Systems

Abstract

This paper presents a nonisolated Three Port Converter (TPC) with a unidirectional port for photovoltaic (PV) panels and a bidirectional port for energy storage. With the proposed topology single power conversion is performed between each port, so high efficiencies are obtained. A theoretical analysis is carried out to analyze all operating modes and design considerations with the main equations are given. A 4kW laboratory prototype is developed and tested under all operating conditions. Results obtained feature on efficiencies higher than 97% for all operating modes and all power levels from light load to full load.
