METHOD TO CONTROL STATIC STABILISED SOURCES OF AC VOLTAGE OPERATING IN PARALLEL FOR COMMON LOAD Russian patent published in 2013 - IPC H02M7/17 H02M7/23 H02M7/493 H02P13/00 

FIELD: electricity.

SUBSTANCE: in the method to control stabilised sources of AC voltage operating in parallel for a common load in addition to operations specified in the invention formula, one of parallel operating sources is selected as master, and others - as slaves, besides, the first and second differential signals of the master source are generated by subtraction of appropriate signals proportional to d - and q - components of total voltage from reference signals for d - and q - components of total voltage, for other slave sources the first and second differential signals are generated by subtraction of signals proportional to d - and q -components of current of the slave source from a signal proportional to d - and q - components of master source current.

EFFECT: increased accuracy of specified distribution of load current between parallel operating sources proportionally to rated capacity of each source in static mode.
