???I am asking, strike that, pleading for help. ??? I've attached a drawing and the Tina schematic of the circuit in question. I am trying to design a voltage regulator for a 200W, 20A motorcycle alternator with field coil - one side to B+, not ground and no permanent magnets. The battery is a 12V, 1.2A motorcycle battery. I am using Tina Pro Version 6 to model the circuit.
I think I'm in the ballpark but need help refining values. I would really appreciate your help.
