For a small generator like the 125 Watt Alternator/Generator in your car, 12 Volts at a couple Amps. For a large 1,200,000,000 Power Plant Generator typical excitation is 600V at 8000A.

excitation voltage is sinusoidal because it is taken from the terminal of alternator but excitation current is non-sinusoidal because it always dc.

AC generators convert rotational energy into AC by moving a static magnetic field through the vicinity of the stator windings. You create this static magnetic field with DC. If you tried to use AC, the magnetic field would be varying, and t...

Some generators are self excited; this means their terminal voltage is fed back to the excitation system to supply power to the rotor of the generator (which makes it into an electromagnet); the more power that is fed back, the stronger the...

When feedback voltage is lost to the AVR, there is still an open-loop control (voltage reference setpoint) as well as an inner stabilizer that will kick into action if the field voltage drops. Thru amplifier action, the field current will b...

I am not sure why they would do such a thing, I take it there is something that increase the speed of the exciter, to get all the way to 150 hertz. It is not going to be sitting on the same shaft without some gearing or it won't produce 150...

Can you give me the make and model of the synchronous generator you are referring to? Then I can determine the internal construction of the field windings. I think, in most such generators the field is powered by a direct current, not an a...
