Abstract

PURPOSE:To increase the switching speed by supplying a sufficient negative bias voltage when the base of a transistor is OFF and expediting the extinction of a stored charge. CONSTITUTION:When a control transistor 1Tr is turned OFF from a conductive state, a pulse voltage of a flyback voltage is generated in a secondary winding Nb1 of a transformer 1T, and a power transistor 1Tr is turned ON. When the power transistor 1Tr is turned ON, the magnetic flux of a trasformer 1T is inceased in the positive direction, and the power transistor 1Tr keeps the ON state. In order to release this state, the control transistor 1Tr is turned ON. At this time, it is necessary to flow a reverse current sufficient to remove the stored charge as a control current. When the magnetic flux in the transformer 1T is set in the negative direction, a negative voltage is induced in the secondary winding Nb1 in the transformer 1T, and said voltage is effectively utilized for turning OFF the power transistor 1Tr.
