Abstract
A common-mode voltage cancellation (CMVC) circuit, is disclosed. The circuit includes a set of input lines arranged to receive a respective phase voltage, and a set of output lines arranged to provide a respective output phase voltage. The circuit further includes a set of coupled inductors, each having a respective primary winding and secondary winding coupled in signal communication at a respective upstream end to a respective input line to receive a respective phase voltage therefrom, each respective phase voltage having a common-mode voltage component. Each primary winding being coupled at a respective downstream end to ground, and each secondary winding being coupled in series between the respective input line and a respective output line. The circuit includes a set of capacitors, each capacitor being electrically coupled to a respective input line and in series with a respective primary winding of the set of coupled inductors.
