  2. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    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 current), and yields a higher average output voltage.

    The top plot shows the individual three phase signals, the middle plot shows the half-wave rectifier output in solid curve and the bottom plot shows the full-wave rectifier output in solid curve. The 'T' in time is the time period of individual signals and V p e a k {\displaystyle \scriptstyle V_{\mathrm {peak} }} is the amplitude of each of ...

  5. 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 ...

  6. Ripple (electrical) - Wikipedia

    en.wikipedia.org/wiki/Ripple_(electrical)

    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.

  7. 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 ...

  8. Pulsed DC - Wikipedia

    en.wikipedia.org/wiki/Pulsed_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 ...

  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.
