Abstract:
An electrical circuit for reducing electromagnetic noise or interference in a power converter. The circuit includes at least one shunt capacitor arranged to connect with a grounded component of the power converter, wherein the at least one shunt capacitor is further arranged to be driven by an active control signal so as to sink a noise current originating from a noise source to the grounded component of the power converter, wherein the noise source is connected to the grounded component via a capacitive path formed by at least one stray capacitors.
