Abstract: The new loosely coupled transformer used for electric vehicle wireless charging system is
designed. The performance of loosely coupled transformer needs to be tested when it is used for electric
vehicle wireless charging system. The Constitution and principle of wireless charging system are describec
in detail. The relationship between the coupling coefficient and the transmission efficiency is analyzed
Based on Maxwell parametric analysis, the proposed coupled structure is analyzed. Particularly, the
relationship of the position and the coupling coefficient is needed to be concerned. The method of co
simulation based on Simplorer software is utilized to analyze the performance of the loosely coupled
trans. The curve of coupling coefficient changing with gap and misalignment is obtained, and the
parameters of voltage and current are obtained. With 200mm gap and no misalignment, the power of the
system with proposed structure reaches 3.65kw, the transmission efficiency is 90.12%. The proposed
loosely coupled transformer satisfies the requirement of eleetric vehicle wireless charging system
