Abstract

A system and method for delivering electrical power-on-demand to at least one load circuit wherein the system operates primarily with reactive power. The method includes inductively coupling power from a source in a primary circuit to one or more load circuits. The system is arranged to store magnetic energy in a core surrounded by planar coils positioned in parallel. The magnetic circuit is toroidal, symmetrical and circuitous. Magnetic energy is transferred between loads through the system. Back currents from the loads are able to be converted to magnetic field energy contributing to the total of stored energy available to the loads. Since the combined energy held in the system is primarily reactive, internal energy losses are small.
