Experimental Design of Wireless Power Transmission Based on Helmholtz Coil

To address the insufficient integration of theory and practice in traditional electrical engineering experiments, a wireless power transfer experiment based on Helmholtz coils was conducted using the circuit principles of electric vehicle wireless charging technology and the existing laboratory equipment. The study investigated the effects of three typical compensation topologies (SS, LCC-LCC, LCC-S) and circuit parameters on transmission performance. The experimental results validated the theoretical model, achieving satisfactory outcomes. This experimental case combines theories such as electromagnetic fields and circuits with engineering applications, featuring strong theoretical comprehensiveness and cutting-edge technology. It effectively stimulates students' interest in learning, cultivates innovative and practical engineering skills. This experiment is constructed using conventional laboratory equipment, suitable for undergraduate teaching and popularization, and can serve as a reference for electrical engineering experimental instruction.
