Abstract (en)

[origin: WO2019228816A1] The invention relates to a method for operating an energy converter (10) that couples a first supply network (12) to a second supply network (14) by electrical energy being converted by means of at least one switch element (22), wherein: - the switch element (22) is operated in a switching operation and - a supply-network current for one of the supply networks (12, 14) is adjusted depending on a comparison of the supply-network current with a reference current, - a first operating mode is provided for the switching operation, in which operating mode an electrical voltage of one of the supply networks (12, 14) is set by means of a PWM method on the basis of the comparison, and - a second operating mode is provided, in which the switch element (22) is therefore switched if, during the comparison, a difference between the supply-network current and the reference current is greater than a first predefined relative switching value and/or is smaller than a second predefined relative switching value, wherein the first and the second operating mode are alternated during the intended operation.
