Abstract:
An apparatus for active feed forward electromagnetic interference (EMI) filtering, including, a noise detection and current reconstruction circuit that receives EMI noise occurring at a noise source, and noise voltage compensation circuit operatively coupled to the noise detection and current reconstruction circuits. The active feed forward circuit generates a noise voltage compensation signal based on the EMI noise reconstructed by the noise detection circuit.
