Abstract
A method for providing an output power of a switched mode power converter comprises the steps of determining a block length and, if a set value of the output power is below a first power threshold, preventing a power flow through the converter in each period of the multiphase AC voltage for at least one blocking interval. Each blocking interval has a duration of one block length. The switched mode power converter has a multiphase AC side with a number N of conductors for receiving a multiphase AC voltage. The number N of conductors is at least three. Power flows into the switched mode power converter through a combination of current-carrying conductors. The block length is defined by a time span between two subsequent changes of the combination of the current-carrying conductors.
