Breaker

Purpose

Ideal AC circuit breaker.

Switches

Description

pict

This component provides an ideal short or open circuit between its two electrical terminals. The switch closes when the controlling gate signal becomes non-zero. It opens when both the gate signal and the current are zero. Therefore, this circuit breaker can be used to interrupt inductive AC currents.

Parameters and Dialog Box

[Picture]

Initial conductivity
Initial conduction state of the breaker. The breaker is initially open if the parameter evaluates to zero, otherwise closed. This parameter may either be a scalar or a vector corresponding to the implicit width of the component. The default value is 0.

Probe Signals

Breaker current
The current through the component in amperes (A). A positive current flows from the left to the right terminal in the above breaker icon.
Breaker conductivity
Conduction state of the internal switch. The signal outputs 0 if the breaker is open, and 1 if it is closed.
