Hello,

I'm trying to do a "simple" setup of charging a capacitor in Simulink.

I'd like to figure out how to limit the current the DC Voltage Supply can source.

Problem:

Power source 1kV at 1 Watt
1uF capacitor in series with 2k Ohm Resistor
Plot time vs. voltage of capacitor from 0V to 900 V

Hi Bryan, you can do this easily is Simscape, though you will have to use a controlled voltage source instead. AD

Ok. I have not dealt with DC/DC converters on a very deep level, but I think you will need some more complexity in your model. There is a DC/DC converter block in the Simscape Electronics library that you can check out. Perhaps this will provide what you are expecting. Or, you can build your own circuit based on the circuit in the documentation.

Interesting, I will give that a try! I was hoping to just start after the DC/DC converter to avoid adding extra "unnecessary" complexity.

EDIT: I can't get it to work. I found a current limiter block, but I can't seem to get it to work either. Could this current limiter block be the way to solve my problem if I could implement it properly?
