Abstract :
This paper presents a simple digital implementation of One Cycle Control used for regulating the current injected into the grid in photovoltaic micro-inverter applications. The digital implementation has been derived by the corresponding analog one by adopting a predictive estimation of the duty-cycle modulating signal. The dc/ac stage has been simulated and tested by using a laboratory prototype demonstrating the applicability of the proposed digital architecture.
