Research on Output Voltage Tracking Technique Based on SWDPT System

Due to the complexity of the oil drilling environment, the parameters of the wireless energy transmission system drift, causing the output voltage to drop, which affects the instability of the backstage circuit. In view of the above problems, this paper designs an energy and telecommunication co-transmission system based on the frequency tracking technology of output voltage stabilization, simulates the parameter changes of the coupling mechanism due to the environmental changes, establishes the model of the coupling mechanism by MAXWELL, and builds the simulation model of the system in MATLAB. The experimental results show that the output voltage of the system has been stabilized at the set value unchanged under the change of system parameters, which proves the feasibility of this design.
