Quasistatic Single Phase Variable Conductor

Single phase variable conductor

Modelica Standard Library

	Description
	The Quasistatic Single Phase Variable Conductor (or Variable Conductor) component connects the voltage $v$ with the current $i$ by i = Gv. The conductance G is given as a real input signal. The model includes a Conditional heat port and temperature dependency.

	Equations
	$i = i_{p} = - i_{n} = G_{actual} v$ $v = v_{p} - v_{n}$ $G_{actual} = \frac{G_{ref}}{1 + α_{ref} (T_{hp} - T_{ref})}$ $ω = {\overset{&period;}{γ}}_{p}$ $γ_{p} = γ_{n}$ $P_{loss} = ℜ (v \overset{&conjugate0;}{i})$ $T_{hp} = {\begin{array}{c} T_{heatPort} & Use Heat Port \\ T & otherwise \end{array}$
