61Demand response — This article is about the electrical concept. For the transport concept, see Demand responsive transport. A clothes dryer using a demand response switch to reduce peak demand In electricity grids, demand response (DR) is similar to dynamic demand …
62Electric double-layer capacitor — Maxwell Technologies MC and BC series supercapacitors (up to 3000 farad capacitance) An electric double layer capacitor (EDLC), also known as supercapacitor, supercondenser, electrochemical double layer capacitor, or ultracapacitor, is an… …
63Ripple (electrical) — The most common meaning of ripple in electrical science, is the small unwanted residual periodic variation of the direct current (dc) output of a power supply which has been derived from an alternating current (ac) source. This ripple is due to… …
64Diode bridge — Three bridge rectifiers. The size is generally related to the current handling capability …
65Buck 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… …
66British Rail Class 74 — Infobox Locomotive name = British Rail Class 74 powertype = Electro diesel caption = 74 003 in BR blue with full yellow ends builder = British Railways’ Doncaster Works; rebuilt BR Crewe Works builddate = 1958–1960; Rebuilt 1967–1968 gauge =… …
67Load regulation — is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in load [cite web|title=Line and Load Regulation for Programmable DC Power Supplies and Precision DC Sources Developer… …
68X-ray tube — An X ray tube is a vacuum tube that produces X rays. They are used in X ray machines. X rays are part of the electromagnetic spectrum, an ionizing radiation with wavelengths shorter than ultraviolet light. X ray tubes evolved from experimental… …
69SEPIC converter — A SEPIC (single ended primary inductor converter) is a DC DC converter which allows the output voltage to be greater than, less than, or equal to the input voltage. The output voltage of the SEPIC is controlled by the duty cycle of the control… …
70Direct current — (red curve). The horizontal axis measures time; the vertical, current or voltage. Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and… …
