As with single-phase rectifiers, three-phase rectifiers can take the form of a half-wave circuit, a full-wave circuit using a center-tapped transformer, or a full-wave bridge circuit. Thyristors are commonly used in place of diodes to create a circuit that can regulate the output voltage.
The characteristics and components of ripple depend on its source: there is single-phase half- and full-wave rectification, and three-phase half- and full-wave rectification. Rectification can be controlled (uses Silicon Controlled Rectifiers (SCRs)) or uncontrolled (uses diodes). There is in addition, active rectification which uses transistors.

Between the circuit's input and output is a diode that performs half-wave rectification, allowing substantial current flow only when the input voltage is around a diode drop higher than the output terminal. The output is connected to a capacitor of value and resistor of value in parallel to ground. The capacitor is charged as the input voltage ...

Mercury rectifier on display in the Beromünster AM transmitter in Switzerland, before being decommissioned.Three-phase full-wave rectifier with six anodes. A mercury-arc valve or mercury-vapor rectifier or (UK) mercury-arc rectifier [1] [2] is a type of electrical rectifier used for converting high-voltage or high-current alternating current (AC) into direct current (DC).
Pulsed DC is commonly produced from AC (alternating current) by a half-wave rectifier or a full-wave rectifier. Full wave rectified ac is more commonly known as Rectified AC. PDC has some characteristics of both alternating current (AC) and direct current (DC) waveforms. The voltage of a DC wave is roughly constant, whereas the voltage of an AC ...
