Photovoltaic system and method of controlling same
A photovoltaic (PV) system is disclosed that provides dynamic regulation of the output of a PV array such that the inverter can safely operate without entering a voltage protection mode. The PV system includes a PV array that generates a direct current (DC) output from received solar radiation and a DC link coupled to the PV array to receive the DC output therefrom. The PV system also includes a DC-to-AC power inverter electrically coupled to the DC link to receive the DC output therefrom and invert the DC output to an AC output and a damping circuit electrically coupled to the DC link and positioned between the PV array and the DC-to-AC power inverter. The damping circuit includes a damping resistor and a damping switch.
