摘要： An inductively powered lamp unit (500) that uses an inductive power pick up comprising a resonant circuit including an inductance (401) and capacitance (402), the induced current circulating in the resonant circuit is limited to a maximum value by a shorting switch (503) that closes a connection across the inductance (401) shorting the resonant circuit. The shorting switch (503) is controlled by a comparator (506) that compares the sensed current with a reference value (510). Voltage control maybe similarly implemented. Power is supplied to LED's (405), control data may also be conveyed through the inductive link. Applications include roadway markers, fire escape indicators, underwater or explosive environmental lighting.

摘要： A contactless inductive power distribution system operating at 10 KHz has a self tuning resonant power supply connected to a resonant primary conductive path 10110, 10111 comprising a pair of parallel litz wire conductors 10110, 10111 each encapsulated within an insulated sheath and supported on a structural monorail beam 10101 on which a plurality of electric vehicles can run. Each vehicle has an electric motor (not shown) capable of deriving power from a resonant pick-up coil 10115 wound on a ferrite core 10102 mounted on the vehicle in close proximity to the primary conductors 10110, 10111. Each vehicle also has switching means 10116 capable of preventing a lightly loaded vehicle from presenting a reduced load to the resonant primary. As shown, this comprises an isolating coil 10116 having a switch (not shown) to switch the coil between an open circuit and a short circuit, so that when the switch is switched from one state to another state the power coupled between the primary conductive path 10110, 10111 and the pick-up coil 10115 is changed.
