Abstract
A power converter system includes an input rectifier configured to rectify a line power having a line energy and a full-bridge isolating converter comprising a transformer, where the full-bridge isolating converter is configured to generate an isolated output voltage based on the rectified line power, and where the isolated output voltage is electrically isolated from the line energy. The power converter system includes a power controller configured to operate the full-bridge isolating converter to generate the isolated output voltage, determine whether the transformer is operating in a flux walk state based on an electric current of the transformer, and perform a corrective action in response to the transformer operating in the flux walk state.
