Modeling and Analysis of Coupling Mechanism Loss in Wireless Power Transfer Systems Based on Partitioned Computation

In a magnetically coupled wireless power transfer (WPT) system, the coupling mechanism experiences coil losses, core losses, and aluminum plate losses due to high-frequency currents during operation. Establishing an accurate loss model can guide the design of the coupling mechanism and help reduce energy losses. This paper employs finite element simulation software and utilizes a partitioned computation method to optimize the loss model of the coupling mechanism. The optimized model offers higher precision, with simulation results more closely aligning with the actual system losses.
