Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge … Wikipedia
Extract, transform, load — Extract, transform and load (ETL) is a process in database usage and especially in data warehousing that involves: Extracting data from outside sources Transforming it to fit operational needs (which can include quality levels) Loading it into… … Wikipedia
Buck converter — A buck converter is a step down DC to DC converter. Its design is similar to the step up boost converter, and like the boost converter it is a switched mode power supply that uses two switches (a transistor and a diode) and an inductor and a… … Wikipedia
Buck-boost converter — Two different topologies are called buck boost converter. * The inverting topology The output voltage is of the opposite polarity as the input * A Buck (step down) converter followed by a Boost (step up) converter The output voltage is of the… … Wikipedia
DC-to-DC converter — An assortment of 78xx series ICs, linear DC DC converters A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. It is a class of power converter. Contents … Wikipedia
Boost converter — A boost converter (step up converter) is a power converter with an output DC voltage greater than its input DC voltage. It is a class of switching mode power supply (SMPS) containing at least two semiconductor switches (a diode and a transistor)… … Wikipedia
