<P>PROBLEM TO BE SOLVED: To provide a power conditioner which can operate a direct-current load efficiently and stably. <P>SOLUTION: The power conditioner comprises: a bidirectional inverter 12 which selectively executes DC/AC conversion to convert a direct-current output based on power generation from a power generation facility 21 to an alternating current, or AC/DC conversion to convert an alternating current from a system 22 to a direct current; a system linked switch 13 which connects the bidirectional inverter 12 to the system 22; a rectifier unit 14 connected to the system side of the system linked switch 13, which rectifies an alternating current from the system 22; a DC output switch 16 which feeds one of the direct-current output based on power generation from the power generation facility 21, the direct-current output of the bidirectional inverter 12 and the rectified output of the rectifier unit 14 to a direct-current load; a storage unit 17 which stores operation modes therein in which mode power is fed to the direct-current load; and a control unit 18 which controls the system linked switch 13 and the DC output switch 16 according to an operation mode and also chooses which power, the direct-current output or the rectified output, to feed to the DC output switch 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
