Controlled Switch
>>Basics>Circuit>Ideal Switches
The component represent an ideal electrical switch. Within the dialog you can choose a voltage
or current controlled switch.
If the control quantity (V or I) is greater than threshold plus hysteresis, the controlled switch
is on. If the control quantity is lower than threshold minus hysteresis, the controlled switch is
off. Because it is an non-ideal switch, you can define an On and Off resistance for the line connection.
The component cannot be used with AC and DC simulation.
You cannot use zero for the on resistance.
Off → On V or I > ( THRES + HYST)
On → Off V or I < ( THRES – HYST)
Dialog Settings
� «Type»
In the list, select Voltage or Current controlled switch.
«On State Resistance»«Off State Resistance»
Defines the resistance for the on and off state. Common parameter type. Enter a numerical
value, a variable, or an expression in the text box or use the pin to connect a quantity.
«Threshold Voltage»«Threshold Current»
Defines the threshold of the controlled switch. Common parameter type. Enter a numerical
value, a variable, or an expression in the text box.
«Hysteresis Voltage»«Hysteresis Current»
Defines the hysteresis of the controlled switch. Common parameter type. Enter a numerical
value, a variable, or an expression in the text box.
«Initial State»
Defines the initial state of the controlled switch. Enter a numerical value, a variable, or an
expression in the text box to define the initial state at simulation start.
