High-voltage direct current
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. [1] Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of ...
The evolution of transmissions
Published: February 27, 2023. The very first automobiles needed a way to transmit power to the wheels. Early methods of accomplishing this were comprised of exposed belts and pulleys, effectively creating a single-speed transmission. There were many different variations, but to get both acceleration and speed, more than one gear was needed.

Reviewing the history of electric power and electrification
A useful but regrettably obscure example is John Casazza''s Development of Electric Power Transmission 10, one of the only works on the important subject of ''wheeling'' power from place to place over increasingly vast distances. What these corporate histories sometimes do well, even if they are not always explicit about it, is to document …
A History of the Automatic Transmission
An automatic transmission is a transmission with no gears but an electronically controlled system that does the shifting. This system''s torque converter helps redirect engine power from the crankshaft to the wheels. The engine produces power at different speeds; if you want more torque or power, it needs to increase its speed (rpm).

dc power transmission
power-handling capability as high as 270 MW were devel-oped for high-voltage dc (HVdc) transmission in the 1960s. A decade later during the 1970s, thyristor valves completely replaced mercury-arc valves due to their ruggedness, reli-ability, low maintenance, and cost and gave real impetus to dc power transmission. AC Versus DC
Basics of Wireless Power Transfer | SpringerLink
The power transmission starts with the AC-to-DC conversion, followed by a magnetron for DC-to-RF conversion at the transmitting side. After broadcasting through the air, the RF/microwave signal captured by the receiving rectenna is rectified into electricity again. ... W.C. Brown, The history of power transmission by radio waves. IEEE Trans ...

Electric power transmission
OverviewHistorySystemBulk transmissionAdvantage of high-voltage transmissionModelingHigh-voltage direct currentCapacity
Commercial electric power was initially transmitted at the same voltage used by lighting and mechanical loads. This restricted the distance between generating plant and loads. In 1882, DC voltage could not easily be increased for long-distance transmission. Different classes of loads (for example, lighting, fixed motors, and traction/railway systems) required different voltages, and so used …
