Piecewise Linear Resistor
Description
Nonlinear resistor defined by a piecewise-linear voltage-current characteristic.
The characteristic is provided as segmented data points, for example (V1, I1), (V2, I2), (V3, I3). Each segment defines the local resistance as the ratio between voltage variation and current variation.
When the operating current is outside the provided data range, the first or last segment is extrapolated. Internally, the component is represented by a voltage source in series with an ideal resistor. These internal values are recalculated when the operating point changes segment, and each segment change is treated by the solver as a discontinuity.
SIMBA returns an error if the input data points are not ordered by ascending current.
Important
The Voltage-Current matrix must have two columns. The first column lists voltage values, and the second column lists the corresponding current values.
Default Values
The default values represent a 1200 V power diode.
