Abstract :
This paper proposes an efficient control approach of photovoltaic (PV) array-based high-frequency link inverter architecture that tracks the maximum available power of a PV array source and synchronously supplies sinusoidal current into the utility grid by using only a single stage of power processing conversion. A feed-forward compensator eliminates the loop gain dependence on the utility grid and keep the input maximum power of PV array during variable grid voltage. Voltage seconds analysis shows that the transformer can be designed as the conventional high-frequency transformer of a DC/DC converter without any low frequency harmonics. Simulation and experimental results show that the full-bridge switches are turning on at zero voltage.
