Abstract
A power supply system for recovering degraded performance of a solar cell due to PID is provided. The power supply system includes a solar cell, a non-isolated type DC/DC converter that boosts a DC voltage from the solar cell input from an input end with a predetermined boosting ratio and outputs a DC voltage from an output end, and an inverter that converts a DC voltage output from the output end of the DC/DC converter into an AC voltage, the power supply system being connected to an external power system for system interconnection, wherein the power supply system includes a potential adjustment device for applying a voltage of an external power system to the solar cell via the inverter to set a ground potential of a negative electrode of the solar cell to positive when an output of the solar cell is smaller than a predetermined value.
