Abstract:
An electric power conversion device supplies electric power of a DC power source from an input part to an output part through a power conversion circuit having a transformer and switches. The transformer has primary and secondary coils magnetically connected. The device has a choke coil, an auxiliary coil and a control part. The auxiliary coil is connected to the output part and magnetically connected to the choke coil. The auxiliary coil is wound to allow a current to flow from a negative-electrode side to a positive-electrode side of the output part when a current flows from the power source to the choke coil. The control part performs a switching control of the switches to supply electric power of the source to the output part through the auxiliary coil to prevent generation of magnetic flux in the primary coil and the current from flowing in the secondary coil.

Claim (Index 3):
The electric power conversion device according to  claim 1 , wherein the switches comprises a first switch, a second switch, a third switch and a fourth switch, the first switch and the second switch are connected in series, and the third switch and the fourth switch are connected in series,\n one end terminal of the primary coil is connected to a connection node between the first switch and the second switch, and the other end terminal of the primary coil is connected to a connection node between the third switch and the fourth switch, the first switch and the third switch are connected to the positive electrode of the direct current power source, the second switch and the fourth switch are connected to the negative electrode of the direct current power source, and the control part performs the switch turned-on control and the switch turned-off control alternately, wherein the first switch, the second switch, the third switch and the fourth switch are turned on simultaneously in the switch turned-on control, and the first switch, the second switch, the third switch and the fourth switch are turned off simultaneously in the switch turned-off control.
