Hi everybody.

I need to apply a concrete current shape into a circuit with several paths with also several inductances and mutual inductances.

To run the simulation I have to include a large parallel resistance, BUT this resistance implies an inaccuracy in the results that can not be allowed.

How can I manage to apply this current wave exactly in the point indicated with the arrow?

Thanks in advance for all possible suggestions,

David

I decided to increase the "original signal" and input it to the current source. Then I make a measurement at the desired point and comparing with the "original signal". I modify the multiplying factor till I reach â really small error.

It is a quite skimpy solution.

Any other idea?

Thanks in advance.
