<p>A separable inductive coupler (10) for transferring electrical power across a dielectric medium using magnetic induction. Its coil geometry allows for easy disassembly of primary (12) and secondary circuits. When primary (12) and secondary (23,25) coils are mated, an extremely low leakage inductance transformer is formed. This provides for good high frequency operation at high power density. The coupler allows electrical power transfer without metal-to-metal contact. The design allows easy removal of the primary (12) or secondary coil (23,25) from the transformer. The coil geometry has very low leakage inductance and very low high-frequency resistance which allows high frequency operation. The power transfer density is much higher than previously achieved with separable inductive couplers. Approximately 6000 watts has been transferred through a version of the present separable inductive coupler having a volume of 25.8 cubic inches, yielding a power density of 230 Watts/cubic inch. The coupler is adapted to provide a safe, convenient and weatherproof device for coupling power to a load, such as an electric vehicle to recharge its propulsion battery. <IMAGE></p> |
