The demand for electric vehicles has increased over the past few years. Wireless power transfer provides more flexibility than traditional plug-in charging technology. Charging couplers are critical components in wireless systems. thermal effect produced by magnetic coupler work will cause temperature of device to rise rapidly, affecting efficiency, power, operation reliability, and service life. This paper modeled analyzed each component's distribution characteristics behavior. Firstly, coupler's mutual inductance circuit model established, analyzes heat generation process. models under three different core distributions component is obtained. parts verified test structure experiment.
