Controllable Capacitance and Inductance

Hello!

I am finding a way to simulate the variable capacitance and inductance in the PSIM. The ceramic capacitor has a capacitance that varies this the DC bias voltage (1) or the inductance can be controlled with the DC current source (2 ). It may need the lookup table to describe that characteristic.

Thank you so much for your attention!
