Grid Connected Inverter
Abstract
This paper presents solar based single phase grid connected inverter system. In such a system, DC-DC converter is both used to boost low PV panel voltage and ensures that the solar panel operates at maximum power while Full bridge inverter injects the maximum power from the solar panel to the grid. The system is reliable because it does not cause control complexity and also it is preferred to obtain a low THD (Total harmonic distortion). But, the main disadvantages of the converters such as a boost or a flyback type are limited voltage gain and low efficiency. In the proposed topology, the DC-DC converter with galvanic insulation and high voltage gain characteristics can connect a low-voltage solar panel to the grid. Simulation results are given for the system which inverts MPPT voltage range of 20-30 V DC to grid voltage of 220 V(rms) at power range of 60-300 W with a unity power factor.
