Design of an isolated full bridge micro inverter

Micro inverter converts direct current into alternating current by using individual solar photovoltaic (PV) panel. A full bridge micro inverter design comprising of high frequency full bridge converter and line commutated inverter is proposed here. Sinusoidal Pulse Width Modulation is suitable techniques among all other voltage control signal techniques. The performance of this inverter is evaluated in terms of Total Harmonic Distortion (THD), power conversion efficiency, California Energy Commission (CEC) efficiency and European Union (EU) efficiency. Simulations results of 400W single phase full bridge micro inverter was performed and it results in maximum power conversion efficiency up to of 95.39% and total harmonic distortion of 2.07%.
