<p>A base system (Figure 8C) generates a three-dimensional magnetic flux field using, for example, a uniquely shaped magnetic material and winding arrangements (x, y, z) that generate multi-frequency multi-directional fields such that their vector sum is the resultant of a power transference surface that sweeps three-dimensionally within the designated area. When a floating coil or winding arrangement together with the appropriate circuitry is placed in the vicinity of the field, the coupling and induction effect produces a current that flows in the conductor that forms the coil. Power can then be successfully transferred bounded by the resultant field regardless of its orientation or height. With the proliferation of Digital Signal Processing (DSP) technology in the Switched-Mode Power Supplies (SMPS) area, the electromagnetic fields can be controlled independently and therefore adaptive control becomes more feasible. This increases the benefits of three-dimensional magnetic flux generation.</p> |
