1. A power converter comprisinga power module havinga power controlling semiconductor element, anda current detector for detecting current inputted into said power controlling semiconductor element or outputted from said power controlling semiconductor element;

  • a control unit for controlling operation of said power controlling semiconductor element; and

    a planar conductive member through which induction current flows at the surface due to electromagnetic induction generated by current flowing through said current detector, whereinsaid current detector hasa conductor electrically connected to said power controlling semiconductor element, anda magnetic detecting unit for detecting a magnetic flux which is generated by the current flowing through said conductor, andthe magnetic detection surface of said magnetic detecting unit being parallel to the surface of said planar conductive member so that said magnetic detecting unit detects a component which is vertical to the surface of said planar conductive member, among magnetic flux generated by the current flowing through said conductor.
