Abstract
A method and an apparatus for setting a feedback power of a converter clocked at a fundamental frequency on the power supply side are disclosed. The converter includes a bridge circuit equipped with controllable semiconductor switches, wherein the semiconductor switches are clocked at the fundamental frequency depending on a desired direction of a power flow through the bridge circuit. Drive signals for the semiconductor switches are derived from the clock pulses at the fundamental frequency and a switch-on delay which depends on a DC link voltage of a DC link connected to the converter. The switch-on delay is determined based on a predetermined characteristic curve that depends on the DC link voltage.
