I am just trying to figue out a question I have about transformers.
I am also looking around the internet but have not found the answer yet.
It might sound a daft question but how does a transformer work with a square wave input....
There are lots of simple inverter circuits on the internet that do this but I always thought the voltage had to be contantly changing to have a changing magnetic field to induce the secondary winding to create an output.
Looking at a time/voltage graph of a square wave ac then the voltage is +ve and constant for a bit and then -ve and constant for a bit. The change from +ve to -ve taking no time.
Does the magnetic field in the core take its time in reversing and hence create an output? .... and is it square wave or has got smoothed out a bit by the magnetism taking its time?
Edit: Thinking about it... does the output become +ve / -ve / +ve / -ve spikes with dead sections between?
Are there any transformer gurus here that can shed light on this?
