To provide a power conditioner capable of supplying the power to a load without interruption by receiving the output of sufficient power from a distributed power supply even when a failure occurs in a commercial power system.
A power conditioner 1 includes an independent converter 12 for supplying the power to an independent power supply path 5 which is independent from an interconnected converter 11. When a problem occur in a commercial power system 3, a control section 13 stops the interconnected converter 11, and causes the independent converter 12 only to operate. When the commercial power system 3 is normal, the control section 13 causes the independent converter 12 to operate prior to the interconnected converter 11 using the power output from a distributed power supply 2. With this, even when a problem occurs in the commercial power system 3, the power conditioner 1 can supply the power to a load 6 which is connected to the independent power supply path 5 in an ordinary state of the commercial power system 3, without interruption by receiving the output of sufficient power from the distributed power supply 2.
