Ideal Thyristor

Ideal thyristor

 Description The Ideal Thyristor component models a thyristor with an off-state conductance, ${G}_{\mathrm{off}}$, and an on-state resistance, ${R}_{\mathrm{on}}$. The parameter ${V}_{\mathrm{knee}}$ sets the voltage which commutates the thyristor. If ${V}_{\mathrm{knee}}, a true value on the Boolean gate input $\mathrm{fire}$ causes the device to go to the on-state. It remains in the on-state, regardless of the value on the gate, until it is commutated (that is, until $v\le {V}_{\mathrm{knee}}$).
 Equations $\mathrm{off}=\left(s<0\vee \mathrm{pre}\left(\mathrm{off}\right)\wedge ¬\mathrm{fire}\right)$ $i={i}_{p}=-{i}_{n}={G}_{\mathrm{off}}{V}_{\mathrm{knee}}+s\left\{\begin{array}{cc}{G}_{\mathrm{off}}& \mathrm{off}\\ 1& \mathrm{otherwise}\end{array}$ $v={v}_{p}-{v}_{n}={V}_{\mathrm{knee}}+s\left\{\begin{array}{cc}1& \mathrm{off}\\ {R}_{\mathrm{on}}& \mathrm{otherwise}\end{array}$ $\mathrm{LossPower}=vi$ $T=\left\{\begin{array}{cc}{T}_{\mathrm{heatPort}}& \mathrm{Use Heat Port}\\ 293.15& \mathrm{otherwise}\end{array}$
