摘要

提出了一种基于状态变量动态特性分类的谐振变换器平均大信号建模方法。将建模技术应用于一种串并联谐振变换器，该变换器在零谐振电流下控制开关。在平均模型的基础上，提出了该谐振变换器的滑模控制器，该控制器具有对外部干扰的鲁棒性和输出电压的良好动态响应。

An averaged large-signal modeling method for resonant converters

An averaged large-signal modelling method for resonant converters is presented, which is based on the classification of the state variables according to their dynamic behaviour. The modelling technique is applied to a series-parallel resonant converter, which is controlled for switching at zero-resonant current. Based on the averaged model, a sliding mode controller for this resonant converter is proposed, which provides robustness in relation to external disturbances and a good dynamic response of the output voltage.
