A Prototype of Block UU Shape Ferrite Cores Inductive Wireless Power Transfer for EV Charger

User’s acceptance of wireless EV chargers is expanded worldwide. In Thailand, previous static wireless power transfers (WPT) were not over 1.0 kW. This study is to design a higher power EV charger’s WPT. In the experiment, the EE55 ferrite core with a 5 mm air gap inductive coil design of WPT was analyzed, constructed, and tested using 0 - 300 V 20 kHz squared wave inverter, performed 1.50 kW, and 88% efficiency to a resistive load. Finally, the block UU shape ferrite IPT with a 160 mm air gap was constructed and tested in the same conditions. The results found that the performance of the IPT was 124 kW and 75% efficiency that lower the design rated.
