Set/Reset Switch

Purpose

Ideal switch with RS-flipflop behavior.

Switches

Description

[Picture]

This component provides an ideal short or open circuit between its two electrical terminals. The switch closes when the closing gate signal (the upper input in the component icon) becomes non-zero. It opens when the opening gate signal (the lower input) becomes non-zero. The Set/Reset Switch provides the basis for all other switches and power semiconductor models in PLECS.

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 switch. The switch 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

Switch conductivity
Conduction state of the switch. The signal outputs 0 if the switch is open, and 1 if it is closed.
