摘要: There are several possibilities to transfer the energy taken from a photovoltaic cell grid. In past, modules used same centralized inverter Nowadays, decentralized preferred because of their versatility harvest larger amount power, even when some total surface covered and do not receive solar irradiation. This paper presents an topology that can be connect module directly The is based on single stage Flyback it quite simple. Furthermore, maximum power point tracking algorithm proposed. system implemented in very simple microcontroller output current, although sinusoidal, its harmonic content lower than limit imposed by IEC 61000-3-2 regulations. A prototype has been built tested.
