A method of calibrating a parasitic metal detection system and a method of collecting calibration data for a parasitic metal detection system

摘要

A system and method for controlling inductive power delivery in an inductive power delivery system, and a method for designing an inductive power delivery system using power calculation are disclosed. A method for controlling inductive power delivery includes measuring characteristics of input power and characteristics of power in a tank circuit, and receiving information from the secondary device. Estimating power consumption based on the measured power characteristics of the tank circuit and the received information, and determining characteristics of the input power measured to determine if there is an unacceptable power loss, information from the secondary device, and estimated power consumption . / RTI A method of designing an inductive power delivery system using power calculations includes varying the distance between the primary and secondary sides and varying the load on the secondary side. Measuring circuit parameters on the primary side and circuit parameters on the secondary side in the tank circuit during the transfer of non-contact energy, for each distance and each load between the primary and secondary sides. The method further includes selecting a formula for describing power consumption in the system during the transfer of non-contact energy based on coefficients and circuit parameters, and determining coefficients using the measured circuit parameters.
