摘要
通过对BUCK电路的零电流开关准谐振变换器的开关过程的分析,简化其开关过程,推导得到一个相对简单实用的非线性模型。该模型可以方便地由MATLAB进行仿真,可用于分析开环和闭环的结构。其优点和准确性可以从仿真结果中得到证明,应用该建模思想可以推广到BOOST,BUCK—BOOST以及其它拓扑电路。
A simple and useful nonlinear model is deduced by analyzing and simplifying the switching process of the ze-ro-current-switching quasi-resonant converters. The model can be conveniently simulated with MATLAB and apply to ana-lyzing the open loop and closed loop structure. The simulation results show its merits and veracity. The idea of the modeling can he extended to BOOST. BUCK-BOOST and other topologies.
