Abstract
A power distribution system to distribute electric power having a source of alternating current of a frequency of 10 kHz or greater, a distribution line connected to the source, and at least one load. The distribution line has two substantially flat conductors separated by an insulating sheet, and an element formed of a material of high relative permeability associated with at least one of the conductors. With use of the system an electronic ballast can be used with dichroic and discharge lamps, with high efficiency and absence of light flicker. Substantial reduction in H field interference due to the high frequency alternating current is achieved with use of the distribution line.
Claims13
An electric power distribution arrangement comprising a source of alternating current having a frequency of 10 kHz or greater, a distribution line connected to said source, the distribution line comprising three layers constituted by two conductors, each of substantially flat configuration with two opposed parallel faces and lying in separate planes, a first of said conductors lying in one plane and a second of said conductors lying in another separate plane in spaced parallelism with said first conductor, the conductors being located in spaced parallelism relative to the parallel faces and being located a short distance apart, and an insulator that separates the two conductors disposed between the two opposed parallel faces of the two conductors of substantially flat configuration, at least one of the conductors included in the three layers of the transmission line being associated with a respective further element formed of a material of high relative permeability, that element comprising a foil secured to a face of the at least one conductor remote from the insulator, the arrangement further comprising at least one load connected to said conductors to receive electric power therefrom.
