Answering your question;

The ONE and ONLY thing a DC CHOPPER does, is converting a DC voltage into a sequential switched DC pulsating voltage.

As what happens when switching the DC on and off.

You will have sequences of the DC voltage and Zero.

Chopping is switching on and off according a repetitive pattern,in this meaning.

NOTHING MORE.

The frequency is a typical parameter for how many times this happens per second. (Expressed in Hz, or cycles per second)

No explanation what it is used for? Like changing the average power content or making DC fit for transformation? To this question a GA from me.
