generator,what is the difference between them

Answer Posted / lashari

In the small Generators the batteries are used for excitation while in big generators the excitor in built in machine on the rotor of generator which is dc small generator to provide excitation current. so there are two types of excitation i) seperately excited and self excited discussed later..

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
