摘要： A power supply device used in an induction type power supply system is provided that includes a power supply coil, an auxiliary coil, a power supply driving module, a auxiliary driving module, a harmonic frequency measuring module, a voltage measuring module and a processing module. The power supply driving module drives the power supply coil. The auxiliary driving module drives the auxiliary coil. The harmonic frequency measuring module measures a resonance frequency of the power-supply coil according to a capacitive and inductive parameter related to the power-supply coil. The voltage measuring module tracks and locks a maximum of an oscillation voltage of the auxiliary coil. When the processing module determines that the resonance frequency is stable and the oscillation voltage decreases more than a predetermined ratio of the oscillation voltage, the processing module keeps the power supply driving module under a non-working status.

摘要： The present invention provides a method of time-synchronized data transmission in induction type power supply system, comprising timers and programs installed in a supplying-end module and a receiving-end module to predict the time for generating the trigger signal at the receiving-end end and perform steps for detecting signals to avoid omission. Under the condition of high power transmission, power output on the supplying-end coil is pre-reduced prior to the time expected for receiving trigger data, making the main carrier wave amplitude decrease in a short time period. In every process of data transmission, timers are mutually calibrated and synchronized again to transmit power without detecting and receiving in the period when no data are expected to be transmitted, thus preventing interference of power load noise and enabling the induction type power supply system to transmit data code stably.

Each of the PS and PR coil modules includes a bar-shaped magnetic conductor, on which an insulated wire is wound into a first coil that is extended along the magnetic conductor to a given length and wound reversely into a second coil, thus producing an induction coil comprising at least the first and second coils. The induction range with given space formed between the first and second coils is used for electromagnetic induction to transmit signals and power energy.
