Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This is a simple TRIAC model based on the extended thyristor model Modelica.Electrical.Analog.Semiconductors.Thyristor.
Two thyristors are contrarily connected in parallel, whereas each transistor is connected with a diode.
Further information regarding the electrical component TRIAC can be detected in documentation of the ideal TRIAC model.
As an additional information: this model is based on the Modelica.Electrical.Analog.Semiconductors.Thyristor.

Attention: The model seems to be very sensitive with respect to the choice of some parameters (e.g., VDRM, VRRM). This is caused by the thyristor model. Further investigations are necessary.
