Powder transistor driving circuit of electromagnetic induction heating device

An electromagnetic induction heating device having a power transistor driving circuit,

• said power transistor driving circuit comprising an induction coil circuit and a driving circuit;
• said induction coil circuit including
• an induction coil connected with an oscillating circuit,
• and at least one power transistor for producing a high frequency switching action,
• said oscillating circuit including a plurality of capacitances and resistances;
• said driving circuit including
• at least two transistors,
• a quick switching circuit connected between said at least two transistors,
• said quick switching circuit including
• at least one inductance having one end connected with a gate of said at least one power transistor for turning said power transistor on or off,
• said at least one inductance having said one end also connected to one of said at least two transistors,
• said at least one inductance having its other end connected to another of said at least two transistors
• whereby said inductance is used to accelerate a reverse current flow of said gate of said power transistor so as to shorten a switching time of said power transistor at the time when said power transistor is turned off.
