Abstract (en)
[origin: WO2007117449A2] A polyphase power conditioning circuit for conditioning power supplied by a power source at a nominal frequency over line, neutral and ground conductors for each of a number of phases includes first, second and third impedances coupled to the line, neutral and ground conductors, respectively, and to output lines for each phase. Each of the impedances prevents power at frequencies greater than the nominal frequency from reaching the output lines.
