4.1 MODELS OF POWER SEMICONDUCTOR DEVICES
SimPowerSystems/Power Electronics includes various models of semiconductor
devices [1]:
1. Diode
2. Thyristor
3. Detailed Thyristor
4. GTO
5. MOSFET
6. IGBT
7. IGBT/Diode
The pictures of the devices are shown in Figure 4.1. For all devices, the option Show
measurement port m is marked. The dialog boxes contain a number of the repeated
lines (elds), so the dialog box of the IGBT-transistor is described rst, and after-
wards, the distinguishing features are indicated for some devices.
The block IGBT models the transistor with the parallel connected snubber ...
