  2. Valley-fill circuit - Wikipedia

    en.wikipedia.org/wiki/Valley-fill_circuit

    An advantage of this design is that it is rather simple. A disadvantage is that the ripple voltage can still be 50% of peak, and have total harmonic distortion (THD) of 35%, which is rather high. A 1998 United States patent , US6141230A, provides a power factor of 0.98 and a THD of 9.61% and is most suited to constant load applications such as ...

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

    Full-wave center-tapped rectifier with capacitor filter. Reducing ripple is only one of several principal considerations in power supply filter design. [nb 1] The filtering of ripple voltage is analogous to filtering other kinds of signals. However, in AC/DC power conversion as well as DC power generation, high voltages and currents or both may ...

  5. 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.

    full-wave rectifier A rectifier circuit that converts both positive and negative parts of the input alternating current waveform into a unidirectional, direct current. fuse A circuit protective device that interrupts excessive current by melting a metal strip. fuzzy control

  7. Envelope detector - Wikipedia

    en.wikipedia.org/wiki/Envelope_detector

    Full-wave rectification traces both positive and negative peaks of the envelope. Half-wave rectification ignores negative peaks, which may be acceptable based on the application, particularly if the input signal is symmetric about the horizontal axis.

  9. 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 ...
