Assignee: EIQ ENERGY, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A power-line/communication system that comprises:
a power-line/communication bus comprised of first and second conductors;
one or more capacitor-based, receiver/transmitter nodes, parallel-connected to the first and second conductors;
a shunt capacitor parallel-connected to the first and second conductors; and
a current transformer having a secondary winding connected in series to the first conductor, which secondary winding is disposed between the shunt capacitor at one end thereof and the receiver/transmitter nodes at the other end thereof;
wherein:
the shunt capacitor is adapted to allow communications signal current to pass while rejecting power current; and
the shunt capacitor impedance at a transmit frequency of communications signals is in a range from about 1% to about 10% of a parallel-combined receive impedance of the receiver/transmitter nodes.
