In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
Diagram of a possible configuration of ring final circuit. Consumer unit is at bottom left. The ring starts at the consumer unit (also known as fuse box, distribution board, or breaker box), visits each socket in turn, and then returns to the consumer unit. The ring is fed from a fuse or circuit breaker in the consumer unit.
A rectifier used in high-voltage direct current (HVDC) power transmission systems and industrial processing between about 1909 to 1975 is a mercury-arc rectifier or mercury-arc valve. The device is enclosed in a bulbous glass vessel or large metal tub.
A ring modulator is an electronic device for ring modulation. A ring modulator may be used in music synthesizers and as an effects unit . The name derives from the fact that the analog circuit of diodes originally used to implement this technique takes the shape of a ring: a diode ring . [ 2 ]
(See also: Rectifier § Rectifier voltage drop) However, a semiconductor diode's exponential current–voltage characteristic is really more gradual than this simple on–off action. [ 8 ] Although an exponential function may appear to have a definite " knee " around this threshold when viewed on a linear scale, the knee is an illusion that ...
Bridge rectifier (four diodes in a package) often changed to "D" for diode BT, BAT: Battery or battery holder: often shortened to "B" C: Capacitor: CB: Circuit breaker: CN: Capacitor network: may be simplified to "C" for capacitor D, CR: Diode (all types, including LED), thyristor "D" is preferred for various types of diodes DL: Delay line: DN ...
The bottom structure uses a lightly doped p-guard-ring at the edge of the sharp corner of the p +-layer to spread the voltage out over a larger distance and reduce the electric field. (Superscripts like n + or n − refer to heavier or lighter impurity doping levels.) Mesa diode structure (top) and planar diode structure with guard-ring (bottom)
