Research on power and signal synchronous transmission technology of multi-terminal magnetic coupling ICPT system

With the continuous development and deepening of wireless power transmission technology, the application of inductively coupled power transmission (ICPT) system is gradually mature, which avoids the wire wear of traditional contact power supply mode, easy leakage, high maintenance cost, and has the advantages of flexible and reliable, low maintenance cost. This paper mainly aims at realizing real-time information interaction while long-term stable power output of medical scanning CT machine, and proposes the synchronous transmission technology of power and signal of multi-terminal magnetic coupling ICPT system. Based on the traditional singleended magnetic coupling structure, the multi-coil parallel structure is proposed, and the FSK signal modulation and demodulation mode is adopted to meet the long-term stable energy output. Finally, a multi-terminal magnetic coupling ICPT system model is built based on MATLAB/Simulink simulation platform, and the feasibility of the system for synchronous transmission of energy and signal is verified.
