Hi,

The output of a half/full wave diode when the diode(s) is connected to an AC transformer and there is no capacitor is called AC or DC? It does not change to negative plot, so I am in doubt what to call it?

Besides I saw an animation of how to generate DC by just sutable using of comotators, the out was like the output of a full wave rectifier without a cap and they called it an DC generator?!

 

unsmoothed DC

Now going it alone

 

But It seems to have periode.

 

in that case it's female unsmoothed DC

unless it goes negative, it is not ALTERNATING, and therefor is not AC

the proper name is half wave rectified unsmoothed DC.

Why half-wave?

If you use a single diode, you rectify only half the waves (either all the positive halves or all the negative halves) hence the term half-wave rectifier. If you use four diodes in bridge configuration ( or two diodes with a center-tap transformer), then it rectifies both halves of the waveform and it's called a full-wave rectifier.

In general the rectified, unfiltered signal from a diode rectifier can be considered pulsing DC or DC with high ripple (it's typical of many battery chargers which have no filter), although it still does have a significant AC component and harmonics (as a spectrum analyzer will measure).

This rectification technique is used in RF circuits (particularly microwave)as a frequency doubler (since a full-wave rectified signal has a fundamental frequency twice the input frequency).

"unsmoothed"? How about non-filtered instead?

ripple DC or un-filtered would be better to call by. still you can call it as DC. it will make current in one direction only.
