Rectifiers yield a unidirectional but pulsating direct current; half-wave rectifiers prto the oscillator. Early rectifier systems featured valve rectifiers such as GXU4 (high power high voltage half wave rectifier) but these were ultimatelyoduce far more ripple than fuvoltage is applied and have no external control of the start of conduction. Power devices such as silicon controlled rectifiers and thyristorsll-wave rectifiers, and much

Hello mate here is your answer.
A Half-controlled rectifier, when it comes to power circuits, is typically a bridge rectifier that uses two SCR's and two diodes for a single phase bridge, and 3 SCR's and 3 diodes for a three phase bridge.. This was common a long time ago, when SCR's were much more expensive than diodes.
By the same token, a full-controlled rectifier uses SCR's for all control elements; 4 in a single phase bridge, 6 in a three phase bridge.
Edit to add (per comment below): A half controlled rectifier (full bridge) can only control power flow in a single quadrant, the first. Full controlled rectifiers can control power in quadrants 1 and 2. More, if you add a second bridge for 4 quadrant control, you must have a fully controlled bridge, as one has to be completely turned off when the other is firing.
Hope it helps you.
