Analysis and comparison of EE-type and CC-type cores for wireless power transfer systems

This study presents a wireless power transfer (WPT) system based on EE-type and CC-type ferrite cores. The push-pull converter is utilized to transfer the power to the secondary side load with a parallel resonant capacitor. The issues of the WPT such as efficiency and air gap are discussed. The analysis and comparison of the EE-type and CC-type cores based on test results is discussed.
