Constant Voltage Output Wireless Power and Information Transmission System Based on ZCS Resonance Point Switching Method

Using the stroboscopic mapping model, the ZCS resonance working point of the ICPT system is obtained, and the single-channel 2FSK signal modulation and demodulation are realized based on the resonance point switching. In order to eliminate the influence of transmission signals of different resonance points on the load voltage, a buck converter is added and the controller is designed. The simulation and experimental results show that the technology can effectively reduce the volume and cost of the ICPT system while realizing wireless power and information transmission and constant voltage output.
