“…The main difference between inductive wireless charging and resonant wireless charging lies in the presence or absence of resonance between the coil's inductance and capacitance. Inductive wireless charging, due to its non-resonant nature resulting in shorter charging distances, is also not considered [39][40][41][42][43]. Therefore, this paper focuses on the study of resonant wireless power transfer technology.…”

This paper presents a study on the impact of circuit parameters on the transmission of electrical energy in wireless power transfer systems designed for intelligent sensing devices within the urban electric power Internet of Things (IoT). Relying on the essential principles of resonant mutual inductance models, the paper conducts an analytical investigation into the phenomena of power-frequency splitting characteristics, efficiency-frequency splitting characteristics, and efficacy synchronization characteristics within wireless energy transmission technologies. The investigation includes a detailed analysis of a wireless power transfer system model operating at 100 kHz, delineating how varying circuit parameters influence the system’s efficiency. Via the utilization of graphical software and computational programming for simulation modeling, this research delved into the dynamics between key parameters such as equivalent load and coupling coefficient and their influence on distinct splitting phenomena. This rigorous approach substantiated the validity of the proposed power-frequency and efficiency-frequency splitting characteristics outlined in the study. Based on the analytical results, it is shown that selecting an appropriate equivalent load or utilizing impedance matching networks to adjust the equivalent load to a suitable size is crucial in consideration of the system’s output power, voltage withstand level, and transmission efficiency. The research findings provide a theoretical basis for the design of wireless power supply systems for non-directly buried cable front-end sensing devices.

To address the issue of metal foreign objects interfering with the charging area and causing a significant drop in the Wireless Power Transfer system’s output power, a method to suppress their influence is proposed. First, a circuit model with detection coils is established, the system’s coupling mechanism is analyzed, a mathematical model for output power is derived, and mutual inductance deviation measure is quantified. Next, a finite element simulation model with detection coils is created to simplify the coil design and analyze mutual inductance deviation measure caused by various metal foreign objects. The misalignment of transmitter and receiver coils are considered, and an improved Grey Wolf Optimizer is introduced to optimize compensation topology parameters, targeting output power. Finally, a simulation model and experimental platform are built, and the proposed method is verified through simulation and experimentation. The method can achieve optimal output power in limited iterations while satisfying constraints, confirming its correctness and effectiveness.
