ABSTRACT:
A non-contact electric inductance circuit for a power source converts input alternating current into signals with harmonic vibration and of high frequency, a coil of a set of corresponding receiver equipment receives the harmonic vibration of the signals to convert it into electric energy; wherein the entire electric inductance circuit has a driving circuit, a harmonic circuit, a feedback circuit, a micro-processing circuit and an adapted-to-adjusting-frequency oscillating circuit integrated with one another. When in operation, the alternating electric current passes to the harmonic circuit after being amplified through the driving circuit, and the feedback circuit transmits the voltage or current of the harmonic circuit to the micro-processing circuit that analyses the value of the voltage or current detected, in order that the entire electric inductance circuit can generate the best harmonic frequency.
