This invention relates to a power converter for use in ACDC power supplies and in particular to a power converter comprising a converter input, a converter output and an output synchronous rectification stage, the output synchronous rectification stage comprises a plurality of switching devices, an output inductor and an output capacitor. According to the invention the output inductor is provided by way of a tapped inductor and there is provided an output reverse recovery device, connected to the tapped inductor to provide an alternative path for the flow of current in the freewheeling period of the output synchronous rectification stage. In this way, the functionality of the power converter, particularly at higher frequencies is enhanced.
