Differential and common mode link dampener
摘要:
A common mode and a differential mode filter(s) between DC links are provided. Each link has a positive rail and a negative rail. The filter comprises a first inductor respectively connected to each of the positive rail and the negative rail, differential mode damping resistance connected in parallel to each of the first inductor, respectively, and a three-wire choke. The three-wire choke comprises a first wire connected in series with the differential mode damping resistance parallel to the positive rail, a second wire connected in series with the differential mode damping resistance parallel to the negative rail and a third wire connected to common mode damping resistance. The common mode damping resistance is galvanically isolated from differential mode transients flowing through the differential mode damping resistance. The differential mode filter has the differential mode damping resistance, and the common mode filter has the common mode damping resistance.
