Abstract
An optimized core design for wireless power transfer system for hybrid vehicle application is proposed in this paper. One of the main challenge of wireless power in hybrid vehicle charging application is the limited distance range and significant efficiency drop under small misalignments between the transmitter (Tx) and the receiver (Rx) coil. Appropriately designed transmitter and receiver coil with core can make the system more tolerant against misalignment. For a planar spiral coil, an optimum core is designed here, using minimum amount of core and higher range of wireless power is achieved with better misalignment tolerance. The proposed model is simulated in Finite Element Analysis (FEA) and verified with experimental data of an implemented system of 3kW power for different gap and misalignment. Implementing the proposed optimized core for the system, the maximum efficiency is achieved much higher compared to the system without core.
