Purpose
Saturable capacitor.

Electrical / Passive Components
Description
This component provides a saturable capacitor between its two electrical
terminals. The capacitor has a symmetrical piece-wise linear saturation characteristic
defined by positive voltage/charge pairs.
Note In order to model a saturation
characteristic with
segments, this component requires
ideal capacitors and
ideal switches. It is therefore advisable use as few segments as
possible.
Parameters
-
Voltage values
- A vector of positive voltage values in volts (V) defining the
piece-wise linear saturation characteristic. The voltage values must be positive
and strictly monotonic increasing. At least one value is required.
-
Charge values
- A vector of positive charge values in As defining the piece-wise
linear saturation characteristic. The charge values must be positive and strictly
monotonic increasing. The number of charge values must match the number of
voltage values.
-
Initial voltage
- The initial voltage across the capacitor at simulation start, in volts
(V). This parameter may either be a scalar or a vector corresponding to the
implicit width of the component. The positive pole is marked with a "+". The
initial voltage default is 0.
Probe Signals
-
Capacitor voltage
- The voltage measured across the capacitor, in volts (V). A
positive voltage is measured when the potential at the terminal marked with
"+" is greater than the potential at the unmarked terminal.
-
Capacitor current
- The current flowing through the capacitor, in amperes (A).
-
Saturation level
- The saturation level indicates which sector of the piece-wise
linear characteristic is currently applied. During linear operation, i.e. operation
in the first sector, the saturation level is 0. The saturation level is negative for
negative charge and voltage values.
