Hydrogen production - Wikipedia production is the family of industrial methods for generating hydrogen gas. As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.

HVDC Power Transmission - an overview | ScienceDirect Topics converter is one of the main components in an HVDC system. The converter used in an HVDC station can either be a 6-pulse or 12-pulse converter. The typical circuit arrangement for a six-pulse converter is shown in Figure 17.12. In a six-pulse converter, the thyristor valve is fired every 60°.

List of high voltage underground and submarine cables ... transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals.
