LLC谐振变换器的高级建模方法：从多谐波分析到小信号模型

This article proposes an innovative approach for accurate modeling of a dc–dc LLC resonant power converter based on extended describing functions. Unlike most of the models available in the literature, which have been developed under the first harmonic approximation, the proposed model allow to take properly take into account the contribution of higher harmonics, providing accurate results even fo...
