To convert AC voltage to a controlled DC voltage. — Controlled rectifiers convert AC to DC with adjustable output voltage.

Thyristor (SCR or TRIAC) — Thyristors allow for controlled switching and voltage regulation.

Firing Angle — The firing angle determines when the thyristor turns on during the AC cycle.

Decrease the output voltage — Increasing the firing angle reduces the conduction period and lowers the average DC output voltage.

1 — A half-wave rectifier needs one thyristor to control the positive half-cycle.
