For rectifier applications, peak inverse voltage (PIV) or peak reverse voltage (PRV) is the maximum value of reverse voltage which occurs at the peak of the input cycle when the diode is reverse-biased. [4] [5] The portion of the sinusoidal waveform which repeats or duplicates itself is known as the cycle. The part of the cycle above the ...
This article is factually correct, open Sedra Smith or Millman Grabel, PIV is defined usually for Rectifiers and are used to specify the max negative voltage the rectifier will have to handle for a particular input circuit. Usually the rectifier is used with a breakdown voltage about 150% of PIV. --TvKimi 12:12, 7 September 2007 (UTC)
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 ...
For purposes of illustration, a basic full-wave diode-bridge rectifier is shown in the first stage, which converts the AC input voltage to a DC voltage. Operation [ edit ]
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.
= is the duty cycle, the ratio of the "pulse" time (when the function's value is not zero) to the full wave period. Most basic wave functions only achieve 0 for infinitely short instants, and can thus be considered as having τ = T , D = 1 {\displaystyle \tau =T,D=1} .
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 ...
