ABSTRACT:
In a power converter having a resonant output circuit transformer coupled to a load circuit, a transformer coupling circuit comprises at least two transformers providing a coupling stage having inductively coupled windings that are in step down relationship to an input and/or output winding of the transformer coupling circuit. This enables the rate of change of voltage in the coupling stage to be reduced and thus correspondingly reduces the transmission of interference from the power converter to the load circuit.
