Voltage Regulators
A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more Alternating current, AC or Direct current, DC voltages. Electronic voltage regulators are found in devices such as Power supply unit (computer), computer power supplies where they stabilize the DC voltages used by the processor and other elements. In Alternator (automotive), automobile alternators and central power station generator plants, voltage regulators control the output of the plant. In an electric power distribution system, voltage regulators may be installed at a substation or along distribution lines so that all customers receive steady voltage independent of how much power is drawn from the line.

7812 Voltage Regulator
__NOTOC__ Year 781 (Roman numerals, DCCLXXXI) was a common year starting on Monday of the Julian calendar. The denomination 781 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Europe * King Charlemagne has his son Pepin of Italy, Carloman (renamed Pepin) anointed "King of Italy", and he is crowned by Pope Adrian I with the Iron Crown of Lombardy. His younger brother Charles the Younger, Charles I is anointed king of Aquitaine, and Louis the Pious (only 3-years old) is appointed sub-king of Italy and Aquitaine, following the conversion of Aquitaine from a Duchy to a sub-kingdom. * Charlemagne meets Alcuin, Anglo-Saxon missionary, in Italy, and invites him to Aachen, where he becomes Charlemagne's chief adviser on Religion, religious and educational matters (approximate date). * The Frankish currency called the ''French livre, livre carolingienne'' is mi ...
