Variable passive components
This section describes variable passive components
Variable resistance, inductance and capacitance is available in Typhoon HIL library of components. Resistance, inductance and capacitance values are defined through a signal input to the corresponding component. Execution rate of the in signal processing part of the components is set to inherit. Variable passive components, their properties window and property descriptions are given in Table 1.

Variable resistor is implemented as a controlled voltage source with mandatory inductor in series that ensures the stability of the component.
Variable inductor is implemented as a current source with an optional resistance connected in parallel. Use of parallel resistor is strongly recommended to eliminate potential topological conflicts, bad cut sets, in the circuit. Value of the parallel resistance should be set with special care to avoid potential stability issues.
Variable capacitor is implemented as a voltage source with an optional resistance connected in series. Use of series resistor is strongly recommended to eliminate potential topological conflicts, bad voltage loops, in the circuit. Value of the series resistance should be set with special care to avoid potential stability issues.
