inˈverter
[f. invert v. + -er1.]
1. One who inverts. rare.
1611Florio, Inuertore, an inuerter, a peruerter. 1621Bp. R. Montagu Diatribæ 44 It was a rare thing then to finde a Cain, a Iudas, an Inuerter, Detayner, Vsurper of Gods Right.
2. That which inverts, or produces inversion.
a. Electr. Also invertor. Any apparatus which converts direct current into alternating current.
1926L. B. W. Jolley A.C. Rectification (ed. 2) xix. 444 In an inverter such as is shown in Fig. 324 a direct current generator G is supplying a steady current to two three-electrode valves and the primary of a transformer. 1947P. Kemp Alternating Current Electr. Engin. (ed. 7) xxviii. 498 Inverters are used for regenerative braking on electric railways. 1961Listener 9 Nov. 773/1 The valve serves not only as a rectifier..but—at the other end of the direct current link—as an invertor, turning direct current into alternating current. 1962A. Shepard in Into Orbit 103 Inverters are used to convert the DC current which comes from the batteries into the AC current required to power some of the systems in the booster. 1970J. Shepherd Higher Electr. Engin. (ed. 2) xxv. 817 D.C. links (with a rectifier at one end and an invertor at the other end of the link) are now commonly used to connect two a.c. power distribution systems together. 1973Wireless World June a7 (Advt.), Models 107A and B are precision built inverters providing 240 volts a.c. from 12 and 24 volt battery systems.
b. Telecommunications. A device that inverts a signal (see invert v. 2 g).
1930Engineering 14 Nov. 625/3 The inverter is usually inserted at the point where the transmitting and receiving signals are combined.
c. Computers. A device which converts either of the two binary digits or signals into the other.
1955R. K. Richards Arithmetic Operations in Digital Computers ii. 32 If the input to an inverter is A, the output is A . 1960T. C. Bartee Digital Computer Fund. iv. 63 Because of its high input resistance, low output resistance, and voltage- and current-gain characteristics, the inverter is one of the most commonly used transistor configurations in digital systems. 1972Millman & Halkias Integrated Electronics vi. 164 The output of an inverter is relatively more positive if and only if the input is relatively less positive. |
