Breaker

Purpose

AC circuit breaker opening at zero current

Library

Electrical / Switches

Description

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

Parameters

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.

Switch model (CPU code generation)

Select the switch model in the generated code.

Fundamental grid frequency (Hz)

This parameter only takes effect when using the non-ideal switch model configuration. In this setup, the breaker can only interrupt the harmonic component of the current which is specified by this parameter. The default is 0.

Probe Signals

Breaker current

The current through the component in amperes \((\mathrm{A})\). 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.
