Igbt Circuit Diagram. The design of the choke l1 used in the above full bridge igbt induction heater circuit can be witnessed in the below given image. As we can see the above image igbt combines two devices n channel mosfet and pnp transistor.
It allows the mosfet and supports most of the voltage. This way there is an extremely high current gain since the insulated gate of the igfet draws practically no current from the control circuitry but the collector to emitter.
