Implements ideal IGBT, GTO, or MOSFET and antiparallel diode
Simscape / Electrical / Specialized Power Systems / Fundamental Blocks / 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.
The internal resistance Ron of the IGBT device, in ohms (Ω). Default is
The snubber resistance, in ohms (Ω). Default is
1e5. Set the
Snubber resistance Rs parameter to
to eliminate the snubber from the model.
The snubber capacitance in farads (F). Default is
inf. Set the
Snubber capacitance Cs parameter to
eliminate the snubber, or to
inf to get a resistive snubber.
If selected, add a Simulink® output to the block returning the diode IGBT current and voltage. Default is selected.
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.
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.
