This paper introduces an interleaved DC/DC converter coupled with a Wireless Power Transfer (WPT) system to ensure charging function for the electric vehicles (EVs) batteries. The dynamic wireless power transfer system charging proposed and studied in VEDECOM institute is detailed. The innovative architecture based on an optimized magnetic coupler associated with a power electronic part is designed for an efficient operation. In this research work, an interleaved Buck boost converter is investigated, the DC/DC architecture is opted due to the variable output voltage of the WPT charging system. The interleaved is able to process more power with reduced circuit ripples and harmonics distortion, and current stress on the battery.
