Abstract

PURPOSE:To prevent the concurrent conduction of switchibg element by providing an inductance in series with a resistor in a feedback circuit. CONSTITUTION:Energy is supplied from a conversion transformer T1 to a load side by the ON and OFF operations of the switching elements Q1 and Q2. The inducatance L is inserted in series with a resistor R3 in the feedback circuit constituted by feedback windings nf1 and nf2 and the resistor R3. When the switching element Q1 is turned from ON to OFF, a voltage is induced in the direction so that the beginning of the winding is positive in the feedback winding nf1, and the voltage is applied to the feedback winding nf2 so that the beginning of the winding is positive. The rise of said voltage is slihgtly delayed than that of the feedback winding nf1. Therefore, the rise in a base winding nB2 is also delayed, and the rise of the collector current of the switching element Q2 is also delayed. Thus the concurrent conduction of the switching elements Q1 and Q2 can be prevented.
