Implements ideal IGBT, GTO, or MOSFET and antiparallel diode
Simscape / Electrical / Specialized Power Systems / Power Electronics
The IGBT/Diode block is a simplified mode of an IGBT (or GTO or MOSFET)/Diode pair where the forward voltages of the forced-commutated device and diode are ignored.
- Internal resistance Ron
The internal resistance Ron of the IGBT device, in ohms (Ω). Default is
- Snubber resistance Rs
The snubber resistance, in ohms (Ω). Default is
1e5. Set the Snubber resistance Rs parameter to
infto eliminate the snubber from the model.
- Snubber capacitance Cs
The snubber capacitance in farads (F). Default is
inf. Set the Snubber capacitance Cs parameter to
0to eliminate the snubber, or to
infto get a resistive snubber.
- Show measurement port
If selected, add a Simulink® output to the block returning the diode IGBT current and voltage. Default is selected.
Inputs and Outputs
Simulink signal to control the opening and closing of the IGBT.
The Simulink output of the block is a vector containing two signals. You can demultiplex these signals by using the Bus Selector block provided in the Simulink library.
Assumptions and Limitations
The IGBT/Diode block implements a macro model of the real IGBT and Diode devices. It does not take into account either the geometry of the devices or the complex physical processes .
The IGBT/Diode block cannot be connected in series with an inductor, a current source, or an open circuit, unless its snubber circuit is in use.
