Abstract
A method for operating at least two pulse-width-modulated inverters connected to a direct-current supply network. The pulse-width-modulated inverters are each actuated via an actuation signal and operated in an operating point. A phase difference is generated between the actuation signals of the at least two pulse-width-modulated inverters by adapting the actuation signal of at least one of the pulse-width-modulated inverters as a function of operating point information describing the operating points of the pulse-width-modulated inverters.
