Notes/Equations
- This component implements a voltage controlled switch. The switch resistance between nodes 1 and 2 varies as a function of the applied control voltage (V _{CON} is the voltage between nodes 3 and 4):
where
For these equations, it is assumed that V1 < V2. If V2 < V1, swap R1 and V1 with R2 and V2 in the equation above.
VCON is defined so that f(V1) = R1 and f(V2) = R2 and provides a smooth transition between states. This is a plot of the switch resistance as a function of the control voltage for V1=1, R1=10, V2=3, R2=10000. - The Model name is optional. If the model name is not specified, then R1, V1, R2 and V2 must all be specified on the SwitchV instance; if the model name is specified, then R1, V1, R2 and V2 on the SwitchV instance are optional and override the values specified in the SwitchV_Model.
- R1 and R2 are model parameters, not the resistance at nodes. Convergence problems may occur if the difference between R1 and R2 is too large.
- V1 and V2 are model parameters, not node voltages. Convergence problems may occur if the difference between V1 and V2 is too small.
- This component works in all analyses, including transient and circuit envelope simulation. If a SwitchV_Model item is not present, the SwitchV Model parameter should be blank.
- DC Operating Point Information lists the DC operating point parameters that can be sent to the dataset.
