Abstract
In a renewable energy-use power system provided with a battery, a DC-DC converter converts the output of a power generation unit that generates electric power using renewable energy into DC power of a predetermined voltage, and outputs the converted power to a DC bus. A power conversion unit converts the DC power of the DC bus into DC power or AC power and outputs the converted power outside the system. A switch is connected between the DC bus and a battery and configured to be switchable between the ON state and the OFF state. The DC-DC converter changes the voltage value of the DC power to be output depending on the ON/OFF state of the switch.
