2. Rectifier - Wikipedia

   en.wikipedia.org/wiki/Rectifier

   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.

3. Mercury-arc valve - Wikipedia

   en.wikipedia.org/wiki/Mercury-arc_valve

   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).

4. Vienna rectifier - Wikipedia

   en.wikipedia.org/wiki/Vienna_rectifier

   The Vienna Rectifier is a unidirectional three-phase three-switch three-level Pulse-width modulation (PWM) rectifier. It can be seen as a three-phase diode bridge with an integrated boost converter .

5. Diode bridge - Wikipedia

   en.wikipedia.org/wiki/Diode_bridge

   A full-wave rectifier is more like a delta connection, although it can be connected to the three-phase source of either wye or delta and it does not use the center (neutral) wire. [ citation needed ] Three-phase full-wave bridge rectifier 3-phase AC input waveform (top), half-wave rectified waveform (center), and full-wave rectified waveform ...

6. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]

7. Active rectification - Wikipedia

   en.wikipedia.org/wiki/Active_rectification

   Whereas normal semiconductor diodes have a roughly fixed voltage drop of around 0.5 to 1 volts, active rectifiers behave as resistances, and can have arbitrarily low voltage drop. Historically, vibrator -driven switches or motor-driven commutators have also been used for mechanical rectifiers and synchronous rectification.
