Hi,
Find the current through C1, voltage across L1 and voltage across R3. Analysis must be done using odesolve block (but of course other methods are welcome).
This challenge has no answer from SNS.
If using normal values of R,L,C, mathcad can solve this circuit by using laplace transform.
However, tau of RL is almost inpulse responce and CR is second order, so calculation soon over 10^304 and stop.
For initial challenge condition, my answer using best effort of mine is this.
Please check or post your answers.
Check the direction of current and voltages of turn on and off times, this is more good answer.
Using your first approach with laplace transform (as using odesolve we cannot obtain any solution so far):
My approach is this with the same results as your:
So, I do not know how you obtained this results. You need to post mathcad file or imgs with complete solution...
I know this that with these input values ttokoro had used initially we can have some plot results, but these values were not first values. Also, he was able to obtain somehow this plot results, which these plot results are more for these values (the first stated values of this problem):
These two pictures are DC and pulse responces of original circuit made by maple 2022. Blue plot shows vR3 and red line shows vL1.
So only the initial and after pulse responces are able to solve. ( I am a biginer of maple. But error message shows same for mathcad, such as over 10^304 like.)
Using mathcad, every DC responce is solved and augment all data set. The tips is not using C value at first but after inverslaplace symbolic results, the value of C is substituted.
