What is a RECTIFIER?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an inverter.
The process is known as rectification, since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium oxide plates, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motor-generator sets have been used. Early radio receivers, called crystal radios, used a "cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) 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, rectifiers can serve as detectors of radio signals.
Depending on the type of alternating current supply and the arrangement of the rectifier circuit, the output voltage may require additional smoothing to produce a uniform steady voltage. Many applications of rectifiers, such as power supplies for radio, television and computer equipment, require a steady constant DC voltage (as would be produced by a battery). In these applications the output of the rectifier is smoothed by an electronic filter, which may be a capacitor, choke, or set of capacitors, chokes and resistors, possibly followed by a voltage regulator to produce a steady voltage.
Something about Stamford
In the 1980s and 90s, Stamford had the third highest concentration of Fortune 500 companies in the country, with 18 companies headquartered in the city. The only two cities that had higher concentrations in the nation was New York City and Chicago.
In 2017, the city had four Fortune 500 Companies, nine Fortune 1000 Companies, as well as numerous divisions of large corporations. In addition to the North American headquarters of Royal Bank of Scotland and a major office of UBS, many specialized hedge funds, asset managers and trading houses are localized in and around the city. This gives Stamford the largest financial district in New York Metro outside New York City itself and one of the largest concentrations of corporations in the nation.
In recent years, various digital media corporations have moved to Stamford as a less expensive place to do production while having easy access to both New York City and Boston. Corporations include NBCUniversal, NBC Sports Group, WWE, A+E Networks, The People's Court, YES Network, ITV America, This Old House, Charter Communications, Thomson Reuters, and Meredith Corporation.
