Peak Loss
An aspect of most rectification is a loss from the peak input voltage to the peak output voltage, caused by the built-in voltage drop across the diodes (around 0.7 V for ordinary silicon p–n junction diodes and 0.3 V for Schottky diodes). Half-wave rectification and full-wave rectification using a center-tapped secondary will have a peak voltage loss of one diode drop. Bridge rectification will have a loss of two diode drops. This reduces output voltage, and limits the available output voltage if a very low alternating voltage must be rectified. As the diodes do not conduct below this voltage, the circuit only passes current through for a portion of each half-cycle, causing short segments of zero voltage (where instantaneous input voltage is below one or two diode drops) to appear between each "hump".
Peak loss is very important for low voltage rectifiers (for example, 12 V or less) but is insignificant in high-voltage applications such as HVDC.

Famous quotes containing the words peak and/or loss:
“In all things I would have the island of a man inviolate. Let us sit apart as the gods, talking from peak to peak all round Olympus. No degree of affection need invade this religion.”
—Ralph Waldo Emerson (1803–1882)
“Nothing that grieves us can be called little: by the eternal laws of proportion a child’s loss of a doll and a king’s loss of a crown are events of the same size.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
