Abstract
[Problem] To provide a power converter capable of suppressing voltage dropping of the smoothing capacitor and suppressing a rush current at the time of power recovery,[Means for Resolution] When it is determined that a bus voltage Vdc detected by a DC voltage detecting unit 24 is equal to or less than a predetermined reference voltage, a control device 20 allows a DC load control unit 23 to stop an operation of a DC load 30.
