Microinverter single phase derived of flyback topology for generating system photovoltaic

This paper proposes develop the implementation of a single-stage single-phase shunt microinverter obtaining four DC-DC converters operating in discontinuous flybacks mode and associated modules in parallel. To validate the experimental research will develop a prototype that will effect the processing power connects a photovoltaic panel with 200 W of power in resistive loads with sinusoidal characteristics. The results obtained in the laboratory show that the microinversor flyback operating in open loop obtains yields close to 90%, being delivered to the load about 180 W. Thus, the ease in construction, using fewer components and enable the experimentally obtained microinversor flyback to perform the DC-AC conversion of photovoltaic systems of small powers connected in single-phase linear loads or connected to the grid.
