Abstract

In the multi-power module application field that the system ground have many noise The narrow-band conducted noise of EMI is big issue This thesis proposes the modified LC Low Pass Line Filters that don’t change old filter body and effection old conduction noise that for suppressing dual narrow-band conducted noise The circuits be composed of induction winding capacitors and resistors By combining LC Low Pass Line Filters with the circuits in series and parallel to produce resonance that dual modified LC Low Pass Line Filters can achieve the dual narrow-band conducted noise suppression The modified LC Low Pass Line Filters which can effectively reduce for electromagnetic interference from the dual narrow-band conducted noise by theoretical analysis added with circuit simulations and results of measured experiments
