METHOD TO CONTROL STATIC STABILISED AC VOLTAGE SOURCES OPERATED IN PARALLEL TO COMMON LOAD Russian patent published in 2010 - IPC H02J3/46 H02M7/48 H02M7/493 H02M7/5387 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in constructing electric power generation or uninterrupted power supply systems. Proposed method comprises amplitude comparison signal is shaped by integration of the difference between amplitude reference signal and that of total signal corresponding to difference between current reactive components. Note that aforesaid difference voltages of active and reactive current components are formed as the difference between appropriate current components of only two sources, namely the difference between current components of the given and the other source, or the difference between current components of the other sources. Note here also that every difference in forming appropriate total signals is used only one time.

EFFECT: higher stability of voltage phase and amplitude on common load, uniform distribution of load current component between sources in static mode.
