    The motor side of the unit in case Nos. 2 and 3 can be driven directly by an AC power source (typically when in inverter bypass), a 6-step double-conversion motor drive, or a 6-pulse inverter. Case No. 1 uses an integrated flywheel as a short-term energy source instead of batteries to allow time for external, electrically coupled gensets to ...

  7. Zigzag transformer - Wikipedia

    en.wikipedia.org/wiki/Zigzag_transformer

    Zigzag transformer. A zigzag transformer winding is a special-purpose transformer winding with a zigzag or "interconnected star" connection, such that each output is the vector sum of two (2) phases offset by 120°. [1] It is used as a grounding transformer, creating a missing neutral connection from an ungrounded 3-phase system to permit the ...
