The practical coil circuits were the prototypes for the modern transformers. (U.S. patent 349,611) William Stanley Jr. was granted 129 patents for a range of products and electrical devices. [1] [6] A selection of patents follow. Significant patents are in bold.
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
D'Arsonval's spark-excited resonant circuits (above) did not produce as high voltage as the Tesla transformer. [2] In 1893 French physician Paul Marie Oudin added a "resonator" coil to the D'Arsonval circuit to create the high voltage Oudin coil, [118] [120] a circuit very similar to the Tesla coil, which was widely used for treating patients ...
Irish priest (and later scientist) Nicholas Callan invented the transformer in Ireland. 1837: English scientist Edward Davy invented the electric relay. 1839: French scientist Edmond Becquerel discovered the photovoltaic effect. 1844: American inventor Samuel Morse developed telegraphy and the Morse code. 1844
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity.
Ottó Bláthy also discovered the transformer formula, Vs/Vp = Ns/Np. [31] Electrical and electronic systems the world over rely on the principles of the original Ganz transformers. The inventors are also credited with the first use of the word "transformer" to describe a device for altering the EMF of an electric current. [30] [32]
Electromagnetic induction was discovered by Michael Faraday, published in 1831. [3] [4] It was discovered independently by Joseph Henry in 1832. [5] [6] In Faraday's first experimental demonstration (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement similar to a modern toroidal transformer).
There, he conducted experiments for creating a transformer. The name "transformer" was created by Bláthy. [citation needed] In 1885 the ZBD model alternating-current transformer was invented by three Hungarian engineers: Ottó Bláthy, Miksa Déri and Károly Zipernowsky. (ZBD comes from the initials of their names). In the autumn of 1889 he ...
