FIELD: electricity.
SUBSTANCE: method is proposed to control multiple power converters, which may be used for coupling with a supplying electric grid, an AC bus, etc. Each power converter comprises a network bridge, operating in compliance with width-pulse modulation (WPM), having one and the same switching period, which generates at least one unwanted harmonic in voltage of the supplying electric grid. The method includes an operation for creation of a WPM switching period of each network bridge with a different time shift relative to the point of time count.
EFFECT: unwanted harmonic in voltage of supplying electric grid will be partially suppressed.
