such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.

The choice of single or three phase depends on the available supply. But a three-phase full wave rectifier provides 6 pulses of DC per cycle, while a single-phase full-wave rectifier provides only two. That makes the output DC easier to smooth.

It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
