  1. Rectifier

    A rectifier is an electrical device that converts alternating current, which periodically reverses direction, to direct current, which flows in only one direction. The process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, copper and selenium oxide rectifiers, solid-state diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motors have been used. Early radio receivers, called crystal radios, used a "cat's whisker" of fine wire pressing on a crystal of galena to serve as a point-contact rectifier or "crystal detector". Rectifiers have many uses, but are often found serving as components of DC power supplies and high-voltage direct current power transmission systems. Rectification may serve in roles other than to generate direct current for use as a source of power. As noted, detectors of radio signals serve as rectifiers. In gas heating systems flame rectification is used to detect presence of flame. The simple process of rectification produces a type of DC characterized by pulsating voltages and currents. Depending upon the type of end-use, this type of DC current may then be further modified into the type of relatively constant voltage DC characteristically produced by such sources as batteries and solar cells.

Dictionary of Nautical Terms

  1. rectifier

    An instrument used for determining the variation of the compass, in order to rectify the ship's course, &c. It consists of two circles, either laid upon or let into one another, and so fastened together in their centres that they represent two compasses, the one fixed, the other movable; each is divided into 32 points of the compass, and 360°, and numbered both ways from the north and the south, ending at the east and west in 90°. The fixed compass represents the horizon, in which the north and all the other points are liable to variation.
