An inductive power outlet is disclosed. The inductive power outlet has a primary inductor, for wirelessly powering an inductive power receiver. The inductive power outlet has a secondary inductor. The primary inductor and the secondary inductor form a resonant frequency. The inductive power outlet comprises a driver generating an oscillating voltage to the primary coil at a frequency higher than the resonant frequency. The inductive power outlet comprises a signal detector. The signal detector comprises a peak detector configured to detect voltage peaks across the primary inductor or current peaks of a current supplied to the primary inductor. The signal detector comprises a processor configured to determine a frequency of either the voltage peaks or the current peaks.

System and method for coded communication signals regulating inductive power transmissions

An inductive power outlet for wirelessly powering a power receiver is presented that comprises a voltage peak detector that is configured to detect voltage changes that are indicative of increase in a system resonant frequency. The inductive power outlet is configured to respond to detected voltage changes by shutting down or issuing a warning, and the voltage peak detector is further used to detect communication signals initiated by the power receiver to the power outlet.

A hybrid power load balancing system configured to manage the amount of power transfer via a plurality of inductive coils is provided. The system comprises one or more power supplies, a plurality of inductive outlets associated with and configured to be supplied power by each of the power supplies for providing power to loads connected thereto, and a load balancer associated with each of the outlets. A power supply and its associated outlets and load balancers constitute a cluster. The load balancers are configured to grant power classes to the outlets to supply at least a minimum required power class to each of the attached loads.

Adjustable inductive power transmission platform

An inductive power transfer system and method for transferring power to an electrical device wirelessly includes an inductive power outlet and an inductive power receiver. During operation, instruction signals are sent from the inductive power outlet to the inductive power receiver. When no instruction signals are transferred, the system is configured to deactivate such that power is drawn by the system only during operation.

System and method for coded communication signals regulating inductive power transmission

An inductive power outlet for providing power to an electric load via an inductive power receiver includes at least one primary inductive coil wired to a power supply via a driver configured to provide a driving voltage across the primary inductive coil such that a secondary voltage is induced in a secondary inductive coil associated with the inductive power receiver. The driver may include a controller configured to receive feedback control signals from the inductive power receiver indicating if more or less power is required. The controller may be further configured to adjust the driving voltage according to the control signals.

System and method for enabling ongoing inductive power transmission

Energy efficient inductive power transmission system and method

An adjustable inductive power transmission platform includes inductive power outlets embedded into adjustable modules having multiple configurations. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The multiple configurations of the adjustable modules allow the position of the inductive power outlets to be adjusted to match the locations of inductive receivers to suit changing requirements.

A current-triggered synchro-rectifier comprising an electronic switch configured to be in its ON setting when the current flowing through its cathode exceeds a predetermined threshold. The electronic switch may include a half-wave rectifier wired to the source terminal and the drain terminal of a MOSFET device, and a current monitor configured to monitor the drain-current flowing through the drain terminal. The current monitor sends a gate signal to the gate terminal such that the MOSFET is switched to its ON state when the drain-current exceeds a first threshold current and the MOSFET is switched to its OFF state when the drain-current falls below a second threshold current. Usefully, the synchro-rectifier may be incorporated into a full-wave rectifier.

Bridge synchronous rectifier

Non-resonant inductive power transmission wherein the driving voltage across a primary inductor oscillates at a frequency significantly different from the resonant frequency of the inductive coupling system. Embodiments of the invention include systems and methods for: power regulation using frequency control, fault detection using voltage peak detectors and inductive communication channels.

Non resonant inductive power transmission system and method

An inductive power transmission platform includes a plurality of inductive power outlets connected to a common driver via individual power switches. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The switches may be configured to remain closed while current passes therethrough. The common driver may be used to manage the power drawn by the transmission platform to each of the inductive power outlets.
