    en.wikipedia.org/wiki/Phase_converter

    An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.

    Demand exists for phase converters due to the use of three-phase motors. With increasing power output, three-phase motors have preferable characteristics to single-phase motors; the latter not being available in sizes over 15 hp (11 kW) and, though available, rarely seen larger than 5 hp (3.7 kW).

    Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]

    The Kando system of the 1930s developed by Kálmán Kandó at the Ganz Works, and used in Hungary and Italy, used rotary phase converters on the locomotive to convert the single-phase supply to three phases, as did the phase-splitting system on the Norfolk and Western Railroad in the United States.

  7. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    Power Converters can include simpler tools such as transformer or more complex like a resonant converter. The term can also refer to a class of electrical machinery that is used to convert one frequency of alternating current into another. Power conversion systems often incorporate redundancy and voltage regulation.
