i want to calculate plots of currents and voltages of the electrical circuit elements for a nonlinear electrical source and to calculate the operational temperature of all elements assuming the thermal resitance model. thanks in advance

</matlabcentral/answers/uploaded_files/23934/rlc.PNG> Data to calculate:

Build the system of ordinary differential equations for voltage on capacitor and current on inductance as state variables. Solve the system of equations using Adams-Bashfort-Moulton of the 4th order algorithm. Plot the current and voltage distributions on ALL elements on separate plots. Calculate the power disspating on each element during a period of time T. (Use Simpson’s 38 rule). Calculate the temperature of each electrical element in steady state using the given termal resistances and formula: Rth=ΔT/ΔP, where ΔT=T−Ta is the temperature between the element and the environment Ta, ΔP is the power disspating on the element. Assume that the surrounding environment has a constant temperature Ta=250oC.

[RahulTandon]

How about solving the circuit (getting the plots) in Simulink using Simscape to model the non-linearities of the circuit elements.

Answer 1

[Lincoln Emilio Bowen Aguayo]

You can use Simscape for measure the voltages and the current, having that, you can calculate de power dissipated and get the temperature.
