  • Single stage EMI filter design to meet EMI requirements
    Publication number: 20230361747
    Abstract: A single stage electromagnetic interference (EMI) filter circuit includes a power source input configured to connect to a power source; an equivalent common mode and differential mode filter including a single inductor having both common mode inductance for common mode filtering and specific parasitic inductance; and a differential capacitance stage connected to the single inductor in parallel, wherein a combination of the specific parasitic inductance and capacitance of the differential capacitance stage are used to provide differential mode filtering.
