2. Phase converter - Wikipedia

   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.

3. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   In Europe, three-phase 230/400 V is most commonly used. However, 130/225 V, three-wire, two-phase electric power discontinued systems called B1 are used to run old installations in small groups of houses when only two of the three-phase high-voltage conductors are used. The phase shift in Europe is 120°, as is the case with three-phase current.

   Wiring schematic for a simplified bipolar-field Gramme-ring single-phase–to–direct-current rotary converter. (In actual use, the converter is drum-wound and uses a multipolar field.) [2] Wiring schematic for a simplified two-phase–to–direct-current rotary converter, with the second phase connected at right angles to the first [3] Wiring schematic for a simplified three-phase–to ...

5. Three-phase electric power - Wikipedia

   Such converters may also allow the frequency to be varied, allowing speed control. Some railway locomotives use a single-phase source to drive three-phase motors fed through an electronic drive. [36] A rotary phase converter is a three-phase motor with special starting arrangements and power factor correction that produces balanced three-phase ...

6. High-leg delta - Wikipedia

   en.wikipedia.org/wiki/High-leg_delta

   Current practice is to give separate services for single-phase and three-phase loads, e.g., 120 V split-phase (lighting etc.) and 240 V to 600 V three-phase (for large motors). However, many jurisdictions forbid more than one class for a premises' service, and the choice may come down to 120/240 V split-phase, 208 V single-phase or three-phase ...

7. Rotary phase converter - Wikipedia

   en.wikipedia.org/wiki/Rotary_phase_converter

   Rotary phase converters are used to produce a single-phase for the single overhead conductor in electric railways. [ citation needed ] Five European countries ( Germany , Austria , Switzerland , Norway , and Sweden ), where electricity is three-phase AC at 50 Hz , have standardised on single-phase AC at 15 kV 16 + 2 ⁄ 3 Hz for railway ...
