摘要 基于对LLC谐振变换器稳态特性的详细分析,推导出一种针对LLC变换器的设计方法。该分析是基于"一次谐波近似"理论,该理论可极大地简化系统的模型,将系统模型线性化,可用经典的交流电路补偿分析方法对系统进行分析。 Based on a detailed quantitative analysis of the steady-state operation of the circuit,a comprehensive design method for a LLC resonant converter was presented.This analysis follows the first harmonic approximation,which tremendously simplifies the system model,leading to a linear circuit,which can be dealt with the classical complex ac-circuit analysis.
