POWER SUPPLY APPARATUS AND CONTROL METHOD OF POWER SUPPLY APPARATUS

A power supply apparatus () is provided with an energy storage device (), a converter () for converting DC output to AC output, and a control unit (). The control unit () controls the converter () such that, when an output current value exceeds a first limit value, the output current value becomes a predetermined value larger than the first limit value by lowering an output voltage value to less than a normal state value.
