Abstract
AbstractThe dual‐load magnetic coupled resonance wireless power transfer (WPT) technology has the advantages of integrated conversion function, higher power density, and higher energy utilization rate. Reasonable coil structure selection and design is a challenge in the dual load WPT system. This article conducts electromagnetic analysis on three types of coil structures: circular–circular, rectangular–circular, and rectangular–rectangular, and uses Ansys Maxwell software to analyze and compare the magnetic field distribution intensity and transmission characteristics of each structure when the coil is offset. The analysis results showed that the rectangular–rectangular coils have stronger offset characteristics. Therefore, the double‐load MCR‐WPT system ultimately adopts the rectangular–rectangular coil structure. The transmitting and receiving coils of the WPT system were wound and tested, and the dual‐load WPT system with rectangular–rectangular coupling coil structures are constructed for experimental verification.
