First Claim
Patent Images
1. A current signal sensing method for a supplying-end module of an induction type power supply system, the supplying-end module comprising a supplying-end coil and a resonant capacitor, the method comprising:
- serially connecting a current sensing element between the supplying-end coil and the resonant capacitor to obtain a current signal corresponding to a current of the supplying-end coil; and
interpreting the current signal to retrieve data of a receiving-end module of the induction type power supply system;
wherein the current signal obtained by the current sensing element is used for determining a time point of the current of the supplying-end coil approaching zero.
