<p>This example compares the behavior of the <strong>ideal thyristor</strong> and the <strong>ideal GTO thyristor</strong> with <em>Vknee=1</em> both. The thyristors IdealThyristor1 and IdealGTOThyristor1 are controlled by an unregular Boolean fire signal. The aim is to show several cases for the fire signal in combination with the state (s&lt;0 or s&gt;0)of the thyristors. Please simulate until 6 seconds and compare IdealThyristor1.v with IdealGTOThyristor1.v, the same with IdealThyristor1.s and IdealGTOThyristor1.s (attention: s is a protected variable in each thyristor). Also compare IdealThyristor1.off and IdealGTOThyristor1.off and have a look at the fire signal (e.g. IdealThyristor1.fire). It can be seen that the IdealGTOThyristor1 reacts on switching off the fire signal whereas the IdealThyristor1 does not show this behavior.</p>
<p>The other thyristors IdealThyristor2 and IdealGTOThyristor2 are controlled by an periodic Boolean fire signal to show a typical use case. Please compare IdealThyristor2.v with IdealGTOThyristor2.v</p>
