Thyristor

– The thyristor is a semiconductor device that can be turned on via a

gate signal. The thyristor model is simulated as a resistor Ron, an

inductor Lon, and a DC voltage source representing the forward

voltage Vf, connected in series with a switch.

The switch is controlled by a logical signal depending on the voltage

Vak, the current Iak, and the gate signal g.

– The Thyristor block also contains a series Rs-Cs snubber circuit that

can be connected in parallel with the thyristor device.
