The extremely high demand for energy and increased demand for fossil fuels has led us to shift our concentration towards new and renewable sources of energy, which are seemingly unlimited sources. They are zero-carbon emitting, thus eco-friendly for the environment. Several issues have been addressed before regarding different topologies for standalone and grid connected inverters with and without microcontroller circuits. Some of them have addressed the introduction of multilevel inverter input using buck boost converters for improving the efficiencies of the output circuit. This paper enlightens the design of single stage photovoltaic inverter which is needed to run AC appliances as loads, which are mostly used as consumable purposes. The design implements MOSFETs as switching devices, which have considerably high switching frequency of 40 KHz, power diodes, inductors, capacitors, solar panel and a battery. The proposed inverter converts the DC output of the PV module into AC directly while maintaining the stability in the output voltage. PSIM software has been used for inverter design. The improved efficiency resulting in 75-90% is due to the minimized voltage drop over the inductor. High frequency operation of the MOSFET switch enables minimized switching losses.
