Set/Reset Switch
Purpose
Bistable on-off switch
Library
Electrical / Switches
Description
This component provides an ideal short or open circuit between its two electrical terminals. The switch closes when the closing signal (the upper input in the component icon) becomes non-zero. It opens when the opening 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
- 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 watts (W). Only defined if the component is placed on a heat sink.
- Switch switching loss
- Instantaneous thermal switching losses in joules (J). Only defined if the component is placed on a heat sink.
