PROBLEM TO BE SOLVED: To provide a bidirectional power source device capable of performing a switch-over between a primary circuit and a secondary circuit in a short time by suppressing generation of a snubber voltage and eliminating biased magnetization remaining in the transformer.SOLUTION: In a bidirectional power source device 10 in which a primary circuit 12 and secondary circuit 13, in which full-bridge circuits are respectively configured with switching elements, are connected with a transformer 11, after completion of energization of a half period of switching elements QH11, QL12 of the full-bridge circuit on a side of supplying the transformer 11 with AC power, the switching element QL12 makes a remaining current flowing through a coil to be short-circuited. |
