Simulink RLC branch dependency on frequency

I am using series RLC branch from simpowersystems. When I enter the capacitance value, there is no option for frequency. This is important in my model, because capacitive impedance changes with frequency.

It depends on ur supply frequency

[Sandhya Jetti]

Thanks Muhammed! that makes sense. Also my supply voltage has pwm steps, so it is not pure sine. How can i measure capacitive impedance?

[Shashank Subramaniam]

It has to do with the discrete or continuous option in powergui.

If you connect an Impedance Measurement block across the component, you can use the " Impedance vs. Frequency Measurement " option in the powergui block to get its impedance over a range of frequencies.

It seems to me that the question here is more how to model variable capacitance as a function of the frequency, rather than measuring the impedance of a component. Is this possible at all?
