ELECTROMAGNETIC COMPATIBILITY FILTER WITH AN INTEGRATED POWER LINE COMMUNICATION INTERFACE
First Claim
1. An integrated electromagnetic compatibility (EMC) filter and power line communication (PLC) interface, comprising:
- a first filter winding and a second filter winding configured as a common mode choke; and
a two-part winding on the common mode choke, wherein the two-part winding comprises (i) a first winding coupled proximate the first filter winding; and
(ii) a second winding coupled proximate the second filter winding, wherein the first winding and the second winding have an equal number of turns, and wherein phasing of the first winding is reversed with respect to the second winding.
