Tesla's AC dynamo-electric machine (AC electric generator) in an 1888 U.S. patent 390,721 In July 1888, Brown and Peck negotiated a licensing deal with George Westinghouse for Tesla's polyphase induction motor and transformer designs for $60,000 in cash and stock and a royalty of $2.50 per AC horsepower produced by each motor.
A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power Converters can include simpler tools such as transformer or more complex like a resonant converter .
The AC Milan team of 1907. A.C. Milan was founded as Milan Foot-Ball and Cricket Club in 1899 by English expatriate Herbert Kilpin.The club claims 16 December of that year as their foundation date, [1] but historical evidence seems to suggest that the club was actually founded a few days earlier, most likely on 13 December.

In signal processing, a digital biquad filter is a second order recursive linear filter, containing two poles and two zeros. "Biquad" is an abbreviation of "biquadratic", which refers to the fact that in the Z domain, its transfer function is the ratio of two quadratic functions:
Fig 1: Classification of three-phase AC-AC converter circuits. [1] Referring to Fig 1, AC-AC converters can be categorized as follows: Indirect AC-AC (or AC/DC-AC) converters (i.e., with rectifier, DC link and inverter), [2] such as those used in variable frequency drives; Cycloconverters; Hybrid matrix converters; Matrix converters (MC)
A direct debit or direct withdrawal is a financial transaction in which one organisation withdraws funds from a payer's bank account. [1] Formally, the organisation that calls for the funds ("the payee") instructs their bank to collect (i.e., debit) an amount directly from another's ("the payer's") bank account designated by the payer and pay those funds into a bank account designated by the ...
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.
