    摘要: Apparatus comprise control circuitry configured to control a line frequency of a microgrid by directing a first set of one or more electrical devices coupled to the microgrid to produce a change in the line frequency through a change in operation of the first set, such that a second set of one or more electrical devices coupled to the microgrid adjusts operation in response to a detected line frequency changeably produced by the first set. Related methods and additional apparatus and methods are disclosed. Apparatus and methods are disclosed that use line frequency and/or line voltage. Apparatus and methods are also disclosed that use control history.

    摘要: The invention is an improvement of the PASC inverter, wherein the improvements include the reduction from two shorting gates per transformer to one shorting gate per transformer and replacement of active control of the shorting gate with passive control of the shorting gate. Further advantages are obtained through the use of anti-parallel gate sets.
