  • Publication number: 20210083522
    Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system and a method for designing an inductive power transfer system with power accounting. The method of controlling inductive power transfer including measuring a characteristic of input power, a characteristic of power in the tank circuit, and receiving information from a secondary device. Estimating power consumption based on the measured characteristic of tank circuit power and received information and comparing the measured characteristic of input power, the information from the secondary device, and the estimated power consumption to determine there is an unacceptable power loss. The method for designing an inductive power transfer system with power accounting including changing the distance between a primary side and a secondary side and changing a load of the secondary side.

  • Patent number: 10862335
    Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system with power accounting. Parasitic metal in proximity to the primary unit can be more accurately detected by accounting for changes in known power losses during operation. The amount of power loss during inductive power supply transfer in an inductive power supply system can vary depending on the alignment of the primary unit and the secondary device. The amount of power loss during inductive power supply transfer can also vary as a function of changes in the operating frequency of the switching circuit in the primary unit or as a function of changes in the secondary device load.

  • Patent number: 10250083
    Abstract: The present invention relates to wireless power supplies adapted to supply power and communicate with one or more remote devices. The systems and methods of the present invention generally relate to a communication timing system that may ensure information being communicated does not overlap with that of another device, preventing data collisions and information from going undetected. With information being communicated in a way that addresses or avoids potential communication issues in multiple device systems, the wireless power supply may control operation to effectively supply wireless power.

  • Patent number: 9154002
    Abstract: A wireless power supply system that detects communications in the input power to the switching circuit. In this aspect of the invention, the wireless power supply includes a detector for generating a signal indicative of the current in the input to the switching circuitry, a band-pass filter for filtering the detected signal, an amplifier for amplifying the filtered signal, a filter for filtering the amplified signal and a comparator for converting the final signal into a stream of high and low signals that can be passed to a controller for processing as binary data stream.

  • Patent number: 8259428
    Abstract: A voltage clamp protection circuit to protect against overvoltage conditions where there is insufficient current to blow a fuse. The voltage clamp protection circuit includes a voltage clamp and a thermal cutoff. The voltage clamp clamps any overvoltage to a clamping voltage. If an overvoltage condition persists for too long the voltage clamp dissipates a sufficient amount of heat to activate the thermal cutoff creating an open circuit that protects the rest of the circuit. The voltage clamp protection circuit may be used in combination with a variety of other protection circuits to provide increased protection.
