Abstract

PURPOSE:To prevent the effect of leakage inductance by a method wherein a secondary winding having an equal winding ratio to a primary winding is wound in bifilar winding and a prescribed low voltage is obtained from a third winding or the like other than the secondary winding. CONSTITUTION:A pulse transformer wherein winding is made on a core so as to induce the electromotive force of a primary winding L1 supplied with an input bias voltage and to generate an output voltage is constituted in such a manner that a secondary winding L2 having a widing ratio of 1:1 to the primary winding L1 is wound in bifilar winding thereon. Moreover, a third winding is wound on the primary and secondary windings L1 and L2, in a low winding ratio of 10:1 to the latter.
