摘要

研究了一种带电容输出滤波器的LLC谐振DC/DC变换器。在现有的基于“一次谐波近似”方法的统一分析的基础上，得到了通过功率器件和谐振电路元件的电流的确定表达式。建立了变换器在ZVS模式下的主要负载特性。

Investigation of an LLC resonant DC/DC converter with a capacitive output filter, Part I - Load Characteristics

A study of an LLC resonant DC/DC converter with capacitive output filter is accomplished. On the basis of an existing unified analysis based on the “first harmonic approximation” method, expressions for the determination of currents through the power devices and the resonant circuit components are obtained. The main load characteristics of the converter at ZVS mode are built.
