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 1):
An electric power conversion device comprising:\n an input part, connected to a direct current power source, comprising a positive electrode side terminal and a negative electrode side terminal; a choke coil connected to the input part; an electric power conversion circuit, connected to the input part through the choke coil, equipped with a transformer and switches, the transformer comprising a primary coil and a secondary coil magnetically connected together; an output part, connected to the electric power conversion circuit, comprising a positive electrode side terminal and a negative electrode side terminal; an auxiliary coil, connected to the output part and magnetically connected to the choke coil, wound in order to allow a current to flow from the negative electrode side terminal of the output part choke coil to the positive electrode side terminal of the output part choke coil when a current flows from the direct current power source to the choke coil, a rectifier element, connected in series with the auxiliary coil, configured to prohibit supply of electric power from the direct current power source to the output part through the choke coil and the auxiliary coil, and to prohibit supply of electric power from the output part to the input part, when a closed circuit including the direct current power source and the choke coil by a switching control of the switches; and a control part configured to perform the switching control of the switches so as to prevent a magnetic flux from being generated in the primary coil, and to prohibit a current from flowing in the secondary coil, and to perform the supply of electric power from being the direct current power source to the output part through the choke coil and the auxiliary coil.
