Abstract

Abstract A secondary winding, divided into a plurality of sections, is provided around a primary winding of the air-core type. First and second diode groups are disposed on four substrates which surround the secondary winding. Diodes in each of the first and second diode groups are disposed on two adjacent substrates so that these diodes are connected in series so as to have the same polarity direction, respectively. The first and second diode groups are respectively divided into a plurality of diode sections. Winding start ends and winding finish ends of winding sections are coupled between the respective two adjacent diode sections. The diode sections disposed on the each substrate are arranged to be spaced apart along the axial direction of the primary winding. One of the diode sections to which induced voltages of the winding sections are applied is disposed on two adjacent substrates, and the other diode section is disposed on the other two adjacent substrates. Positions of these diode sections are shifted along the axial direction of the primary winding. Therefore, the diode sections to which the induced voltages of the winding sections are applied are disposed on different substrates and are not on the same plane.
