Abstract:
1. A power conditioning circuit for conditioning power supplied by a power source at a nominal frequency over conductors in a polyphase system, comprising: a first phase conductor; a second phase conductor; a first inductor connected in series between the first phase conductor and a first output line, wherein power supplied by the power source to the first output line flows through the first inductor; and a second inductor connected in series between the second phase conductor and a second output line, wherein power supplied by the power source to the second output line flows through the second inductor; wherein an inductance of each of the first inductor and the second inductor increases when power at frequencies greater than the nominal frequency flows through the first phase conductor and the second phase conductor, thereby blocking power at frequencies greater than the nominal frequency from reaching the first output line and the second output line.
