PROBLEM TO BE SOLVED: To obtain a multi-output transformer control device and a power conversion device using the same, suppressing increased AC resistance of each winding if there is an unused winding in the multi-output transformer.SOLUTION: A power conversion device 100 includes: power converters 1-4 connected to a power supply or loads 5-8 to perform power conversion; a multi-output transformer 10 including a plurality of windings connected to the power converters 1-4; a circuit and switches 21-24 for making conductive each AC current from the windings 11-14; and a control device 9 for controlling each AC current flowing through the windings 11-14 to be switched on and off. Here, the circuit for making conductive the AC current in the windings 11-14 is constituted by resistors 31-34 and capacitors 41-44 connected in series. |
