  2. Three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Three-phase_electric_power

    A rotary phase converter is a three-phase motor with special starting arrangements and power factor correction that produces balanced three-phase voltages. When properly designed, these rotary converters can allow satisfactory operation of a three-phase motor on a single-phase source.

    en.wikipedia.org/wiki/Mathematics_of_three-phase...

    When three-phase is needed but only single-phase is readily available from the electricity supplier, a phase converter can be used to generate three-phase power from the single phase supply. A motor–generator is often used in factory industrial applications.

    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.

  5. Rotary phase converter - Wikipedia

    en.wikipedia.org/wiki/Rotary_phase_converter

    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).

  6. HVDC converter station - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter_station

    Either two three-phase units or three single-phase units can be used. With the latter variant only one type of transformer is used, making the supply of a spare transformer more economical. Converter transformers operate with high flux Power Steps In the Four Steps of the Converter per cycle, and so produce more acoustic noise than normal three ...

  7. HVDC converter - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter

    The two-level converter is the simplest type of three-phase voltage-source converter [29] and can be thought of as a six pulse bridge in which the thyristors have been replaced by IGBTs with inverse-parallel diodes, and the DC smoothing reactors have been replaced by DC smoothing capacitors. Such converters derive their name from the fact that ...
