Well, for starts, it's not a valve for a fuel injector. But you have a point. Maybe I shouldn't bother so much in cloning the exact waveform and concentrate rather in controlling with precision its open and closing cycle instead... which is what's really important. It's just that I'd like it to behave as closely as possible to what it's originally been doing. And on the other hand, I've become very curios about how its controlling circuitry is doing what it's doing.A bit late for this question, but your post #1 said "I need to replicate the way a magnet is being energized by a controller". Unless I've missed something, it's not clear why? Given that you have accesss to a machine designed to drive the valve, why the precise waveform replication being attempted here? If you simply want to use the valve other than with its original machine, won't a simple peak-and-hold drive (as used for a fuel injector) work for you?
I guess we've reached the point in which the only way to know for sure is to actually build the thing... We'll have to wait and see... Thanks for your input!
EDIT: I think I understand your question now... I'm trying to replicate what the controller is doing because I want to later bypass it and modify the valve's behavior
