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 ...
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 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.
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)

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 ...
