摘要

本文比较了与高频变换器和高功率密度相关的两种空芯变压器的几何形状:一种是逻辑的环形，一种是创新的圆柱形。在这些拓扑结构中对制造、耦合参数、体积和漏磁进行了检查。效率象征着电力电子的一个关键参数，必须在尺寸和功率之间进行优化权衡。提出的创新结构允许在相同的效率下大幅提高转换器的功率密度

A new design of an air core transformer for Electric Vehicle On-Board Charger

This paper compares two geometries of air core transformer, relevant for high frequency converters and high power densities: One logical toroidal, one innovative cylindrical. The manufacturing, the coupling parameter, the volume, and the flux leakage are examined in these topologies. The efficiency symbolizes a crucial parameter on power electronics, and a trade-off must ever be optimized between size and power. The proposed innovative structure permits to strongly increase the converter power density for an identical efficiency
