Set/Reset Switch

Purpose

Ideal switch with RS-flipflop behavior.

Library

Switches

Description

pict

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]

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 corresponding to the implicit width of the component. The default value is 0.
Thermal description
Switching losses, conduction losses and thermal equivalent circuit of the component. For more information see chapter Thermal Modeling.
Initial temperature
Temperature of all thermal capacitors in the equivalent Cauer network at simulation start. This parameter may either be a scalar or a vector corresponding to the implicit width of the component.

Probe Signals

Switch conductivity
Conduction state of the switch. The signal outputs 0 if the switch is open, and 1 if it is closed.
Switch temperature
Temperature of the first thermal capacitor in the equivalent Cauer network.
Switch conduction loss
Continuous thermal conduction losses in watt (W). Only defined if the component is placed on a heat sink.
Switch switching loss
Instantaneous thermal switching losses in joule (J). Only defined if the component is placed on a heat sink.
