I got one simple question which i'm sure you will find easy to answer.
Namely, if we feed transformer with pulsed DC, output is AC as demonstrated here:

and here

What's confusing me is this...
How do we explain this in comparison with alternator..
Lets say north pole of rotor magnet approaches the coil and voltage reaches the peak as it comes closest to the coil. As it starts moving away voltage drops and reaches 0. This is first half-cycle.
Then south pole starts approaching and voltage rises in opossite direction, then falls to 0 and cycle repeats.
Now... Same thing happens in transformer, only solid state.
Feeding pulsed dc to the primary is the same as if alternator's rotor poles are both north or both south, each time they pass near the coil they induce voltage in same direction.
So if this action would produce pulsing DC in a generator, why does it produce AC in a transformer?
I think question is clear, but if it's not i will gladly clearify.
