摘要：
A resonant network design method is proposed for double-sided LCC compensated WPT(Wireless Power Transfer) converters. On the basis of suppressing the harmonic current, reducing the volume of magnetic components, and almost transferring the rated power under maximum distance and maximum lateral misalignment, the electrical parameters of all components in the resonant network, including LCT(Loosely Coupled Transformer), can be determined, according to the constraints of the rated power and switching frequency. A corresponding size design method for LCT with circular planar spiral coils and ferrite cores is proposed. The range of LCT size can be theoretically estimated based on the mutual inductance under maxi-mum distance and maximum lateral misalignment, and then the optimal size of LCT is searched with a small amount of finite element simulation. A prototype with the rated output power of 4.5 kW is designed and constructed, and the experimental results verify the correctness of the proposed method. © 2022, Electric Power Automation Equipment Press.
