Hi,

I want to make a spice simulation with a time varying capacitor. Is it possibel to do that in LTSpice or PSpice e.g. with a control voltage. As far I know with LTSpice it is just possible to vary the charge. But I have to change the capacitnace and keep the charge constant to simulate an electrostatic energy harvester.

I'm thankful for any advice!!!

You can change the capacitance in LTspice using a voltage control but I don't think it will maintain a constant charge in the capacitor as you want.
 

It's surely possible with behavioral sources, similar to the modelling of nonlinear semiconductor capacitance.
