Implementation of photovoltaic system into microcontroller

In this paper we have proposed a photovoltaic system connected to the grid (220V/50Hz). The electric system is composed by a DC/DC and DC/AC converters. A maximum-power-point-tracking (MPPT) technique is used to operate in the optimum power condition. This operation is assured by the DC/DC converter. The Dc/Ac converter allows the adaptation of the PV system to the grid. The hysteresis technique is used to generate the output current waveform. All the command algorithms are implemented in a microchip microcontroller.
