Abstract
The present invention relates to a method for operating a resonant power converter. The resonant power converter has a primary stage and a secondary stage, at least one of which is actively operated and includes a half-bridge or full-bridge inverter having a pull-up switching device, coupled in parallel with a pull-up antiparallel diode and a pull-down switching device, coupled in parallel with a pull-down antiparallel diode, comprising the steps of alternately turning-off and turning on the pull-up and pull-down switching devices according to a periodic switching scheme, wherein after turning-off one of the switching devices the complementary switching device is respectively turned on after a delay time; and initiating an error handling, if after turning-off of one of the switching devices a non-conductance state of the antiparallel diode of the complementary switching device has been determined.
