Breaker

Purpose

Ideal AC circuit breaker.

Switches

Description

[Picture]

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]

Width
The width of the component. This affects both the width of the electrical ports and the width of the gate input signal. The default is 1.
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 with the 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.
