Question:

Who knows how the double IGBT of the electromagnetic oven forms a composite tube?

Who knows how the double IGBT of the electromagnetic oven forms a composite tube?

Answer:

IGBT is a composite tube consisting of a SHM (bipolar power high speed switching tube) and a MOS (insulated gate type FET), and the connection is similar to that of Darlington transistors. Among them, SHM is a current controlled transistor, and MOS is a voltage controlled transistor, so it is called full control.
IGBT overload capacity, larger power. A damping diode is normally connected between the B pole and the E pole of the IGBT. IGBT at work when adding a control signal on the G pole, the gate drive is relatively large, generally greater than the ordinary SHM and V-MOS
