ABSTRACT


In order to meet the application requirements of inductively coupled power transmission systems in mobile high-power equipment, the structure of dual pickup coils can be used to increase the output power of the system. The mobile dual pickups ICPT system has the characteristics that the output voltage varies greatly and the signal is easily interfered during the movement. A mobile dual pickups ICPT system based on the LCL compensation network is designed. The method of adding a buck-boost circuit on the secondary side is used to regulate the output voltage. On the basis of establishing the small-signal model of the Buck-boost circuit, a proportional-integral-differential (PID) controller and a fuzzy PID controller are designed. In the MATLAB simulation platform, the voltage stabilizing effect of the PID controlled mobile dual-pick ICPT system and the fuzzy PID controlled mobile dual-pick ICPT system are compared. The simulation results show that the fuzzy PID-controlled mobile dual pickups ICPT system has faster response speed and smaller overshoot.


Keywords: ICPT, mobile, LCL compensation network, Voltage regulator control
