摘要
本文介绍了LLC谐振变换器中两种矩阵变压器模型的集成原理。通过对变压器绕组原副边的电流进行傅里叶分解,分析其在不同次谐波下电流的路径。最后利用Dowll—维模型对绕组损耗进行理论计算,并与软件仿真Maxwell在涡流场场的仿真结果进行对比。
In this paper, the integration principle of two matrix transformer models in LLC resonant converter is introduced. The path of current in primary side and secondary side of transformer under different harmonic components is analyzed by Fourier decomposition. Finally, winding loss is calculated by Dowl1f's 1-D model, compared with results in Maxwell, a simulation software, under eddy current field.
