Off-Grid Single Phase Micro-Inverter System

Abstract

In most of the households appliances, AC electricity are mostly used. This electricity are easily available but renewable energy is increasing now a days as there is shortage of traditional fissile fuel and it also hazardous to the environment. Such form of electricity can be obtained by converting the DC electricity generated by the solar panels using power electronics devices. There are so many types of inverter configuration are available which can be used for such purpose. Dealing with hundreds of watts of energy, micro-Photovoltaic (PV) type inverters can convert solar energy of each PV panel to the utility individually, with significant improvement of overall system reliability and also have a several advantages over the other topology like tuning the output of each panel, less sensitive to overheating problems etc. This paper presents a case study of a single-phase micro-PV inverter. Circuit analysis and its parameters calculation are carried out in details and demonstrated through simulation based on MATLAB/Simulink. The result proves the analysis of the circuit and provides theoretical validation for further work in research.
