Abstract
Modified control scheme for a single-stage voltage converter for voltage conversion between a single-phase AC grid and a DC grid. In this regard, it is provided that, in pulse-width-modulated controlling of a full-bridge circuit, one pulse per half period is divided into a plurality of sub-pulses. In this way, an RMS current in the leakage inductance of the transformer of the voltage converter can be reduced.
