The Quasistatic Single Phase Variable Capacitor (or Variable Capacitor) component connects the voltage $v$ with the current $i$ by $i=j\mathrm{\ω}Cv$. The capacitance C is given as a real input signal.

The abstraction of a variable capacitor at quasistatic operation assumes $\stackrel{\.}{C}\ll \mathrm{\omega }C$.

$i\=i_p\=-i_n\=j\mathrm{\omega }Cv$

$v\=v_p-v_n$

$\mathrm{\omega }\={\stackrel{\.}{\mathrm{\gamma }}}_p$

${\mathrm{\gamma }}_p\={\mathrm{\gamma }}_n$
