Cet article propose une méthode de blindage actif à bobine unique pour le chargeur sans fil de véhicule aérien sans pilote pour la réduction du champ magnétique de fuite. Un système de blindage proposé élimine le champ magnétique de fuite généré par les bobines d'émission et de réception en générant le champ magnétique d'annulation. Afin d'améliorer l'efficacité du blindage et de préserver l'efficacité du transfert de puissance, les paramètres de conception de la bobine de blindage, notamment le rayon et les spires, seront analysés. Sur la base de l'analyse de la conception de la bobine, l'efficacité du blindage et l'efficacité du transfert de puissance seront estimées. De plus, la méthode de contrôle du courant de blindage correspondant à l'intensité et à la phase du champ magnétique de fuite sera décrite. Un système de blindage proposé a été vérifié par des simulations et des expériences en termes d'efficacité totale du blindage et de mesures d'efficacité du transfert de puissance. La simulation et les résultats expérimentaux montrent qu'un système de blindage actif proposé a atteint 68.85 % de réduction moyenne du champ magnétique de fuite avec 1.92 % de dégradation de l'efficacité du transfert de puissance. L'efficacité du blindage et la variation de l'efficacité du transfert de puissance selon la conception de la bobine ont été vérifiées expérimentalement.

Abstract: This paper proposes a single coil active shielding method of wireless unmanned aerial vehicle charger for leakage magnetic field reduction. A proposed shielding system eliminates the leakage magnetic field generated from the transmitting and receiving coils by generating the cancelling magnetic field. In order to enhance shielding effectiveness and preserve power transfer efficiency, shielding coil design parameters including radius and turns will analyze. Based on the analysis of coil design, shielding effectiveness and power transfer efficiency will estimate. In addition, shielding current control method corresponding to leakage magnetic field strength and phase will describe. A proposed shielding system has verified by simulations and experiments in terms of the total shielding effectiveness and power transfer efficiency measurements. The simulation and experimental results show that a proposed active shielding system has achieved 68.85% of average leakage magnetic field reduction with 1.92% of power transfer efficiency degradation. The shielding effectiveness and power transfer efficiency variation by coil design has been experimentally verified.
