This paper focuses on design and development of a solar PV inverter capable of delivering photovoltaic energy to load in efficient and cost effective manner so that common people can use it. The solar inverter in this paper is considered for a stand-alone solar PV system, for operation of single phase AC load at grid frequency and voltage. Interfacing the solar inverter with AC load involves three major tasks. One is providing regulated output of 230Vrms AC. Second is, it should provide output at 50Hz frequency. Third is, it should have sine wave output. The major challenges to be addressed are, boosting the DC voltage of Solar Module and converting it to regulated AC voltage. So this paper proposes a solution by dividing the whole Inverter system into two major stages: DC-DC Converter and DC-AC Inverter. In the DC-DC Converter stage, Half-Bridge Push-Pull topology is used which implements a high frequency transformer. In the DCAC inverter stage, full bridge topology is used impleme...
