In photovoltaic system, the specifications of solar array is changed as open circuit voltage and short circuit current because of cell temperature and solar radiation. A boost converter of this system connects between output of photovoltaic system and DC link capacitor of grid connected inverter as controlling duty ratio. Therefore to supply stable voltage to the grid, a boost converter is need to keep certain voltage output. Considering the capacitance and the resistance of boost converter, this paper designed proper digital controller.
