<P>PROBLEM TO BE SOLVED: To solve the problem that when a parallel winding two-coil structure is used for one core as a current smoothing inductor between an AC power supply and a switching circuit, a leakage current path becomes long to generate a factor of noise generation. <P>SOLUTION: In the power conversion device which converts a single-phase alternating current into a direct current or converts a direct current into a single-phase alternating current through switching operation of a semiconductor element, the inductor which is inserted between the single-phase alternating current and switching circuit and smooths a current is provided with a first winding for supplying a current of one phase of the single-phase alternating current to a common iron core and a second winding for supplying a current of the other phase of the single-phase alternating current, the first winding and second wiring being wound around the iron core in mutually opposite directions to make currents flow through the windings in mutually opposite directions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
