Abstract Abstract— A level 2 charging standard has been proposed by cooperated Electric Vehicle (EV) manufacturers with a power rating from 2.5 to 19.2 kW. The time to fully charge the EV battery can be reduced to between 0.7 and 2.9 hours under home or public charging conditions. Hence, the EV’s on-board charging system requires high power density and a high frequency transformer to fulfill the design requirements of a light-weight, compact, and high power charging system. This paper introduces a High Frequency Coaxial Transformer (HFCT) with >99.5% power efficiency accompanied by an optimization method for its leakage inductance (Leq) and intra-winding capacitance (Cps). An investigation of the shielding effect of the HFCT has been conducted by using the Finite Element Method (FEM) based numerical technique.
