Micro-inverter for solar power generation

A micro-inverter that takes as input the DC power generated by a solar panel (about 250W) and delivers it directly as AC power to the mains line is presented. The micro-inverter has been designed with discrete components, as it is common practice, since there are no silicon technologies that can be used to integrate the complete circuit and the passive components. The proposed micro-inverter has been extensively simulated and is currently under realisation. The obtained conversion efficiency is greater than 95% and the total harmonic distortion at the output is less than 0.4%.
