摘要：

This paper presents the impact of the switching frequency variation to the power transfer efficiency of a wireless power transfer converter. An experimental demonstrator is used to as a model for this study. The transmitter use Wurth Elektronik wireless power charging coils, 24 mu H, 10%, which is installed across the output of high frequency half-bridge inverter. The switching frequency is varied from 10kHz in steps of 10kHz until 100kHz. The distance between the coils is fixed at 10mm. The receiving coil is fed with a high frequency full-bridge rectifier and a DC load. Experimental results show that the power transfer efficiency varies when the switching frequency is increased. The power transfer efficiency reached its peak at 72% when the switching frequency is at 30kHz.
