Abstract

In a conventional power supply system, it was difficult to quickly activate a motor load or the like after performing switching to an isolated operation. A power conditioner of the present invention comprises: a DC-DC converter part for converting a direct-current power from a direct-current power source into a given voltage; an inverter part for converting a direct-current power from the DC-DC converter part into an alternating-current power; a switch disposed between an alternating-current power output end of the inverter part and a utility power source; and a control part for controlling an output current of the alternating-current power from the inverter part, wherein, in response to opening the switch to cause switching to the isolated operation, the control part is operable, when a given condition is not satisfied, to control the output current such that the output current does not exceed a first upper limit preliminarily determined based on a rated output current value of the power conditioner, and, when the given condition is satisfied, to control the output current such that the output current does not exceed a second upper limit greater than the first upper limit.
