by using inverators

Answer / bidu

An inverter increases the DC voltage, and then changes direct current to alternating current before sending it out to power a device.
These devices were initially designed to do the opposite i.e to convert alternating current into direct current.
Since these converters could basically be run in reverse to accomplish the opposite effect, they were called inverters.

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)
