    Analysis of Wireless Charging System for Low-Power Appliances
    (Institute of Electrical and Electronics Engineers Inc., 2024) Mangamuri, R.; Kuriti, C.S.; Divvi, S.S.; Mallikarjuna, B.; Kishan, D.
    Wireless power transfer stands out as a transformative technology that provides a hassle-free, secure, and effective method for charging of power appliances without the constraints of cables. In this paper, performance analysis of a wireless mobile charging system (lower power appliances) based on a well-established principle electromagnetic induction has been carried out. The system comprises transmitter and receiver circuits featuring wireless power transfer coils. These coils are designed and simulations using ANSYS Maxwell software to analyze the impact of coil misalignment on mutual inductance and coupling coefficient variations of the wireless charging system. The electromagnetic coupled coils are deployed in a charging circuit model designed in MATLAB/Simulink model to demonstrate its dynamic behaviour, showcasing the system's capability to generate a stable 5 V DC voltage for lower power appliances. This study highlights the practicality of optimizing the design of wireless charging system. © 2024 IEEE.
