Renewable Energy Source Fed High Step Up Dc-Dc Converter for Distribiution Grid Applications

Abstract

Low voltage photovoltaic systems require highly efficient converters to deliver as much as possible energy to the load with high gain DC voltage conversion. This concept presents an efficient step-up DC/DC boost converter using couple inductor and single switch. The advantage of proposed DC-DC converter is it absorbs the energy of leakage inductor and provides wider possible range of output power, using a single semiconductor switch with low voltage rating and soft turn on results in lower switching losses and therefore high efficiency. The Total circuit configuration is developed and results are analyzed using Matlab/Simulink software.
