20.500.12556/DKUM-89848 Optimization of a circular planar spiral wireless power transfer coil using a genetic algorithm Circular planar spiral coils are the most important parts of wireless power transfer systems. This paper presents the optimization of wireless power transfer coils used for wireless power transfer, which is a problem when designing wireless power transfer systems. A single transmitter coil transfers power to a single receiving side. The performance of the wireless power transfer system depends greatly on the size and shape of the wireless power transfer system. Therefore, the optimization of the coils is of the utmost importance. The main optimization parameter was the coupling coefficient between the transmitter and the receiver coil in the horizontally aligned and misaligned position. A genetic evolutionary algorithm was used to optimize the coil, according to the developed cost function. The algorithm was implemented using the MATLAB programming language. The constraints regarding the design of the coils are also presented for the problem to be analyzed correctly. The results obtained using the genetic algorithm were first verified using FEM simulations. The optimized coils were later fabricated and measured to confirm the theory. wireless power transfer coil optimization genetic algorithm coupling coefficient measurement brezžični prenos energije optimizacija genetski algoritmi meritve sklopnega koeficienta true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/electronics © 2024 by the authors Članek v reviji 2024-08-14 11:21:10 2024-08-14 11:21:11 2025-07-23 03:11:05 0000-00-00 00:00:00 2024 0 0 12 str. št. 5, št. članka 978 let. 13 March 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-10-05 2023-11-01 2024-03-04 004.5 187854595 10.3390/electronics13050978 2079-9292 electronics-13-00978.pdf electronics-13-00978.pdf 1 8709160B4F1A27FBE9496F516F16F43B 6ef37d3b3d7656fc02440714e9d8d1ee503c477d6ff309d00dfbe738a046f7c0 c21546e0-66de-11f0-b4a7-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193925 https://www.mdpi.com/2079-9292/13/5/978 0 c6bc1602-66de-11f0-b4a7-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193926 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
