摘要
Abstract
The original coil and secondary coil coupling degree influences the voltage of original LC circuit,so a lowfrequency identification circuit is designed.In the state of identification,the secondary circuit changes its compensation capacitor rhythmically according to a certain frequency,the resonant frequency and the coupling coefficient of original and secondary coil were changed.So that the value Q of the primary LC circuit and the inductor peak voltage will be changed.The primary LC circuit is tested whether it produces the corresponding high or low voltage to achieve the purpose of identification.If identification is successful,the primary circuit works properly else waits in a low-power loss state.关键词
