Driver igbt circuit

As far as driving IGBT is concerned, it resembles a MOS-FET and hence all turn-on and turn-off phenomena com-ments, diagrams and Driver circuits designed for driving MOSFET apply equally well to an IGBT. Therefore, what follows deals only with MOSFET models. N+ Co CN+ Cp CGD GATE Electrode SOURCE METALIZATION P-BASE RB N-DRIFT CDB Depletion boundaries. Fig. 2b. Fig. 2b illustrates an IGBT with internal flywheel diodes. The FGA25N is rated at V, 25A. Voltage C-E sat at 25A is V. An important factor is collect-emitter saturation voltage. The following are used in inductive heating circuits. FGPF is rated V a V C-E V at 70A. IHW20NR3 V 20A V. Fig. 3. Fundamentals of MOSFET and IGBT Gate Driver Circuits The popularity and proliferation of MOSFET technology for digital and power applications is driven by two of their major advantages over the bipolar junction transistors. One of these benefits is the ease of use of the MOSFET devices in high frequency switching applications.
