Inductive power distribution system

a power distribution system and inductive power technology, applied in the direction of inductance, electric variable regulation, rail devices, etc., can solve the problems of difficult driving at an acceptable brightness level, affecting the efficiency of inductive power transmission, so as to achieve the effect of increasing the effective distance between the electroluminescent panel and the source of inductive power and widening the spa

Abstract

Inductive power transfer across an extended gap (100) from a primary conductor (119) is provided by means of a resonant intermediate loop comprised of capacitor (118) with inductor (117) carrying a larger resonating current, that can in turn generate an inductive field to be collected by a pickup coil (120). This process and device find application in an electroluminescent advertising panel.

Description

[0001] This application is a division of co-pending application Ser. No. 09 / 423,364, filed on Nov. 8, 1999, which is the national phase of PCT International Application No. PCT / NZ98 / 00053, filed on May 4, 1998, under 35 U.S.C. .sctn. 371. The entire contents of each of the above-identified applications are hereby incorporated by reference.

[0002] This invention relates to a power supply for an electroluminescent display, and to the use of inductive power transfer to provide power across an extended gap between a primary inductive trackway and a secondary pickup device, for a range of purposes including motive power, battery charging and lighting, including lighting using electroluminescent panels.

[0003] Inductive power transfer, although contactless, has in most applications in the prior art using primary pathways required that the configurations shall include ferromagnetic cores and that the secondary or pickup shall be quite closely placed in proximity to, or about the primary cond...
