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 cope with such nuisances, previous studies have assessed different resonant compensation circuits [8][9][10][11]. It was noted that the occurrence of mismatched parameters in the resonant architecture would induce current harmonics [12][13], which was followed by the evaluation of generation source with signal analysis [13][14][15][16].…”

This article proposes an enhanced wireless power transfer (WPT) for automated guided vehicles (AGVs) considering disturbance suppression. The study is motivated because existent resonant methods may induce unexpected disturbances, affecting the efficiency of power transfer and disturbing the voltage gain. This paper is, therefore, focused on the suppression of disturbances as well as the realization of an effective wireless power transmission. Moreover, by considering that the output voltage is often affected by misaligned charging, the system design has included the gain-frequency control along with an early detection of coil misalignment. It is anticipated that through this proposed approach, the constant-voltage output can be achieved while the efficiency of power transfer is improved as well. To validate the practicality of this approach, the hardware prototype is tested with a significant decrement of disturbance interference during the wireless power transmission, supporting the feasibility of the method for AGV charging applications.INDEX TERMS Wireless power transfer, disturbance suppression, automated guided vehicle.
