  2. Vacuum tube battery - Wikipedia

    en.wikipedia.org/wiki/Vacuum_tube_battery

    The "B" battery is used to provide the plate voltage. It is sometimes colloquially referred to as a "dry battery" (although there is no reason why a "wet" battery of suitable voltage could not be utilised for the purpose). The filament is primarily a heat source and therefore the "A" battery supplies significant current and rapidly discharges ...

    Some specify which end of the filament is to be powered by the positive side of the filament power supply (usually a battery). All have glass bodies that measure from 0.285 to 0.400 inches (7.2 to 10.2 millimetres) wide, and from 1.25 to 2.00 inches (32 to 51 millimetres) in overall length.

    en.wikipedia.org/wiki/Rutherford_(rocket_engine)

    The Rutherford engine uses dual brushless DC electric motors and a lithium polymer battery. It is claimed that this improves efficiency from the 50% of a typical gas-generator cycle to 95%. [ 20 ] However, the battery pack increases the weight of the complete engine and presents an energy conversion issue.

    A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threa­ded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.

  6. Multi-level converter - Wikipedia

    en.wikipedia.org/wiki/Multi-level_converter

    Modular multi-level converters (MMC) were investigated by Tricoli et al in 2017. Although their viability for electric vehicles (EV) was established, suitable low-cost semiconductors to make this topology competitive are not currently available (as of 2019). [2] In 1999, Tolbert described the use of MLC for battery operated electric motors. [3]
