Un modelo de enlaces inductivos asimétricos para aplicaciones de transferencia de energía con receptores miniaturizados

This study presents a novel circuit model for an asymmetric inductive link based on planar square one-turn inductors (PSOI). The model is based on a PSOI scheme and a mutual induction expression previously reported. Unlike existing models, the proposed model is accurate when the inductors operate near their self-resonant frequencies. Additionally, a method is introduced to measure the coupling level of the asymmetric link (i.e., factor A) using a vector network analyzer. Materials and methods: Ne proposed model was simulated and experimentally evaluated using a case study involving a PSOI operating near its self-resonant frequency. Results: Ne model’s predictions were consistent with both simulations and experimental values obtained for the tested link. Conclusions: Ne proposed model accurately captured the energy transfer process in the case study, demonstrating its effectiveness and precision under operational conditions close to the inductors' self-resonant frequency.
