Research on composite resonator network with onstant—current output for current—fed ICPT systems

  • In order to solve problem of constant current wireless power supply of different sensors used in coal mine safety monitoring and control system, a composite resonator compensation network for wireless power supply were studied based on current—fed ICPT system,the necessary conditions of the compensation network for realizing constant output were derived, and influences of the implementation mode of soft switch and the system parameters on output characteristics and input impedance angle of the system were analyzed. The network can obtain different output gain through reconfiguration and parameter configuration of compensation element without redesigning loosely coupled transformer, which simplifies hardware circuit. The experiment results show that the proposed composite resonator compensation network can achieve load independence of the primary coil current and output current, and satisfy soft turn off of switching tube. The resonant compensation networks also can be used to realize the constant current power supply of different sensors used in coal mine safety monitoring and control system, which is beneficial to improve reliability of coal mine safety monitoring and control system and adaptability of different loads.
