Active Filter Techniques for Reducing EMI Filter Capacitance
Switching power converters are widely used due to their excellent efficiency, but they inherently generate ripple. Passive low-pass LC filters have been traditionally employed to meet ripple and EMI specifications [1]. These passive filters can contribute considerably to the volume and weight of a power converter. In particular, capacitors can become relatively large in order to meet strict rip...
متن کاملDesign And Simulation Of Integrated EMI Filter
The design and simulation of an integrated common mode filter (CMF) for differential data lines, like the USB 2.0 interface, is presented in this paper. The device is manufactured in a bipolar semiconductor process for the integration of diodes protecting sensitive CMOS circuits against damage by Electrostatic Discharge (ESD). The filter is formed by planar coupled coils that are processed in c...
متن کاملParasitic Capacitance Cancellation of Inte - Grated Emi Filter Using Split Ground Struc - Ture
Abstract—A convenient method for canceling the parasitic winding capacitance of integrated electromagnetic interference (EMI) filter is proposed. Based on the concept of split ground structure, mutual inductances and structural capacitances can be appropriately utilized to expand the effective frequency range in common mode (CM) noise suppression. Compared with the former approaches, it require...
