WIRELESS POWER TRANSMISSION VIA INDUCTIVE-COUPLING USING MAGNETS

摘要

The disclosed couplers operate in a “near field” mode, meaning energy, whether used to transmit data or power, is transferred through magnetic induction using a ∂i/∂t circuit (meaning a change in current over a change in time), such as by using inductive transmission and receive coils in which resistors and/or other components such as diodes are placed into series and/or in parallel with the coils and used to control the shape of the pulse, e.g. its voltage and/or frequency. In an embodiment, one connector comprises a voltage comparator which comprises a hysteresis circuit adapted to be centered at a predetermined no pulse voltage for use in data transmission.
