摘要： An inductively powered sensor system includes a primary conductive path 100 capable of being energized to provide an electromagnetic field in a defined space 1. An inductive power pick-up 120 is associated with a sensor 124 and is capable of receiving power from the field to supply the sensor 124. The system includes a first sensing means to sense the power available to the pick-up 120 and control means to increase or decrease the power available to the sensor dependant on the sensed power available. A method of inductively powering a sensor, an inductively powered sensor and an animal enclosure including one or more primary conductive path of an inductive power supply are also disclosed.

摘要： A wireless power transfer apparatus for capacitive-inductive power transfer has a primary and a secondary device separated by the conductive member. The primary device has at least two transmitter plates configured to be capacitively coupled with the conductive member to induce a current flow and generate a magnetic field in the conductive member. The secondary device is connectable to a load and provided with a receiving coil configured to be inductively coupled with the conductive member.

摘要： The present invention provides a power supply for an inductive power transfer (IPT) system, comprising a current-fed push-pull resonant converter comprising a parallel-tuned resonant tank and a pair of switches enabling selective shorting of the resonant tank; and a controller adapted to control a shorting period of the resonant converter by selectively operating the switches. Methods for controlling an IPT power supply are also disclosed. The power supply may be controlled to regulate the output of an IPT pick-up inductively coupled with the power supply in use, or to operate at a zero voltage switching (ZVS) frequency.
