ABSTRACT:
A power transistor driving circuit for use in an electromagnetic induction heating device comprises an induction coil circuit and a driving circuit. The induction coil circuit is provided with an induction connected with an oscillating circuit made up of capacitances and resistances. The oscillating circuit is provided with at least one power transistor for producing a high frequency switching. The driving circuit comprises at least one quick switching circuit provided with two transistors between which a resistance and an inductance are connected therewith in series. One end of the inductance is connected with the gate of the power transistor for accelerating the reverse current flow of the gate so as to shorten the switching time of the power transistor and to reduce the switching power loss of the power transistor at the time when the power transistor is turned off.
