Hello,
I'm trying to simulate (transient run) a power dependant resistor, the resistor is used to dump an high energy capacitive bank (like an RLC circuit). During the fast discharge, the resistor temperature rises due to Joule effect and it's value change.
I think to use behavioural source to model the resistor.
What I'm not able to do is to get the power variation (between 2 time steps ?) in order to calculate the temperature rise: delta RxI? = mass x heat capacity x delta Temperature. Then i will use the temperature to compute the resistance (Temperature don't need to be linked with the LTSpice Temp variable).
Any tips ? Even if it's not the appropriate method I'm sure that ltspice is able to do it !
This is a common for power electronics ...
Thanks for your help or comments !!
