  2. Diode bridge - Wikipedia

    en.wikipedia.org/wiki/Diode_bridge

    A diode bridge is a bridge rectifier circuit of four diodes that is used in the process of converting alternating current (AC) from the input terminals to direct current (DC, i.e. fixed polarity) on the output terminals. Its function is to convert the negative voltage portions of the AC waveform to positive voltage, after which a low-pass ...

  3. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    Full-wave rectifier, with vacuum tube having two anodes. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Mathematically, this corresponds to the absolute value function. Full-wave rectification converts both polarities of the input waveform to pulsating DC (direct ...

  4. Precision rectifier - Wikipedia

    en.wikipedia.org/wiki/Precision_rectifier

    Precision rectifier. The precision rectifier, sometimes called a super diode, is an operational amplifier (opamp) circuit configuration that behaves like an ideal diode and rectifier. [1] The op-amp-based precision rectifier should not be confused with the power MOSFET-based active rectification ideal diode.

  5. Active rectification - Wikipedia

    en.wikipedia.org/wiki/Active_rectification

    Active full-wave rectification with two MOSFETs and a center tap transformer. Replacing a diode with an actively controlled switching element such as a MOSFET is the heart of active rectification. MOSFETs have a constant very low resistance when conducting, known as on-resistance (R DS(on)). They can be made with an on-resistance as low as 10 ...

  6. Diode - Wikipedia

    en.wikipedia.org/wiki/Diode

    Electron flow is the reverse of conventional current flow. [1][2][3] A diode is a two- terminal electronic component that conducts current primarily in one direction (asymmetric conductance). It has low (ideally zero) resistance in one direction and high (ideally infinite) resistance in the other.

  7. 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).

  8. Envelope detector - Wikipedia

    en.wikipedia.org/wiki/Envelope_detector

    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 ...

  9. Bridge circuit - Wikipedia

    en.wikipedia.org/wiki/Bridge_circuit

    In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
