isolation transformer is a 1:1 transformer. its basic
principle is same as that of ordinary transformer. only the
difference is it can`t step up or step down the voltage. it
provides only isolation between primary and secondary.
strikly speaking that isolation transformer provides more
safety for electrically operated equipment like hand
drilling machines, electric shaving kit etc.

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)
