    I want a design of a circuit used to control the voltage supplied to the magnetic field of ac generator.

    The circuit Job (in breif):
    -supplying the generator field with 12v dc in normal cases.
    -raising voltage supplied in case of loading a motor to accomodate the drop in voltage occured in its input (which is 220vac).

    For clarification...

    You have an engine of some kind running an externally excited alternator?

    You want to increase the excitation voltage when the alternator output voltage drops and/or when the engine slows down?
