2. Rectifier - Wikipedia

   en.wikipedia.org/wiki/Rectifier

   "Full-wave" versions with two separate plates were popular because they could be used with a center-tapped transformer to make a full-wave rectifier. Vacuum tube rectifiers were made for very high voltages, such as the high voltage power supply for the CRT of television receivers, and the kenotron used for power supply in X-ray equipment.

3. Ripple (electrical) - Wikipedia

   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 ...

4. Center tap - Wikipedia

   en.wikipedia.org/wiki/Center_tap

   Low-frequency mains transformers often have center taps. Historically, rectifier costs were high, so DC power supplies with a center-tapped transformer and two diodes ...

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 ...
