Abstract
A common-mode voltage cancellation (CMVC) circuit, is disclosed. The circuit includes a first set of coupled inductors, each having a primary winding defining a first polarity, and a secondary winding. The secondary windings are electrically coupled in series. Each primary winding receives a phase voltage having a common mode voltage component from a respective input line. The circuit includes a second set of coupled inductors comprising at least one primary winding and at least one secondary winding The at least one primary winding receives a second voltage from the series connected secondary windings of the first set of coupled inductors. Each at least one secondary winding is coupled in series with a respective input line such that the common mode voltage component received on input lines will be reduced at an output of the set of secondary windings.
