Abstract

In this paper, a stand-alone photovoltaic (PV) system based on a Double Ended Forward Converter (DEFC) is presented. The proposed converter is specified for 48 V, 100 W applications as most of the equipment used in telecommunication and aircraft fall in this range. The literature has limited potential application of DEFC in PV systems. The research work deals with an in-depth study of DEFC and proposes an improved DEFC for PV applications with battery backup. Besides, a bi-directional dc-dc converter for the battery is integrated to track the Maximum Power Point (MPP) of the PV generator. The converter is examined under variable irradiance and load conditions, and the analytical analysis of boundary conditions are implemented. The converter’s architecture also ensures built-in I-V curve tracing for the identification of MPP of PV generator. It offers low voltage stresses across switches and avoids sinking power supply and core resetting circuits. The topology’s behavior is analyzed based on MPP achievement and maintaining output under different conditions of battery backup availability, environmental, and load conditions. The PV system architecture is designed and analyzed theoretically and verified with simulations on the PSIM software.
