Abstract

A secondary side device for a transmission and receiving system in which the magnetic field of the coil is utilized to generate an induced electromotive force for contactless transmission and receiving system, comprising: a power induction coil which mutually induces to receive power with no contact from the primary side circuit at an power angular frequency <omega>1. The power induction coil is composed of mutual induction couplers, the power angular frequency <omega>1 of the primary side circuit overlaps with the signal angular frequency <omega>2 for transmission and receiving in the signal induction coil, the signal induction coil links in parallel to the resonant capacitor with one end as the grounding signal via signal angular frequency <omega>2; a comparator compares the input signal by means the voltages at both end of the capacitor and uses the power angular frequency <omega>1 as the standard frequency for controlling output; and the power angular frequency <omega>1 will be used as standard frequency for processing the frequency, and active power source will be a end for the grounding controller.
