High Power Wireless Power Transfer Efficiency and EMI Co-Optimization based on Fast Field-Circuit Co-Simulation
Abstract
This paper presents a fast, general-purpose power transfer efficiency and electromagnetic interference co-optimization method for high power wireless power transfer systems. Constraints considering inverter zero voltage switching, total harmonic distortion of the rectifier current, inverter power factor and magnetic field leakage are included in the disciplined optimization problem. In order to reduce time consumption, fast calculation of electromagnetic field is derived by leveraging the linearity of the coil structure. An application using SAE-J2954 Recommended Practice shows that optimization time can be reduced from 24 hours to 2 hours.
