ABSTRACT:
An inductive load drive device using a DC--DC converter circuit with which a high voltage is obtained by the discharge of electromagnetic energy stored in a coil to a capacitor, in which a bias is applied to the magnetic core of a coil (L) with the use of a permanent magnet (Mg) in the direction opposite to the magnetic flux induced by a current so as to increase the electromagnetic energy stored in the coil (L) and make it possible to perform efficient discharge with a small coil.
