VariableCapacitor

Ideal linear electrical capacitor with variable capacitance

Library

Electrical/Analog/Basic

Description

The linear capacitor connects the branch voltage v with the branch current i by

VariableCapacitor_equation1

The capacitance C is given as input signal (top).

It is required that

VariableCapacitor_equation2

To avoid a variable index system, C = Cmin,

VariableCapacitor_equation3

where Cmin is a parameter with a very small default value.

Parameters

    VariableCapacitor_0

  • Cmin [F] : (Cmin): Scalar.

Ports

  • Port 1 at left position: implicit input fixedport numbered 1.
  • Port 1 at top position: implicit input fixedport numbered 2.
  • Port 1 at right position: implicit output fixedport numbered 1.
