Optimized Folded Coil Designs for Wireless Charging Chambers with Even Distribution of Magnetic Flux Density
2024 IEEE Applied Power Electronics Conference and Exposition (APEC)(2024)
Abstract
The concept of using folded coils to uniformize the magnetic flux density inside wireless charging space frames has been validated by a cubic wireless charging chamber. In this paper, the distribution of flux density inside the cubic wireless charging chamber is further optimized by finding out the best-folded ratio around 33%. The method is also extended to find out the optimal folded ratio of an octagonal prism-based wireless charging chamber around 72.5%.
