全桥LLC谐振变换器的研究
资料介绍
为使直流电源控制系统实现转换效率高、输出范围宽,对全桥LLC谐振拓路结构进行研究。基于全桥LLC谐振电路建立合理的数学模型,此数学模型是一种高阶非线性系统,需要进行近似化处理得到可用的空间状态方程。根据空间状态方程和PI控制原理为直流电源系统设计双闭环控制器。最后在Simulink仿真平台上建立全桥LLC谐振变换器双闭环仿真模型,对仿真结果进行分析。
In order to make the DC power control system achieve high conversion efficiency and wide output range,the full-bridge LLC resonant extension structure is studied.A reasonable mathematical model is established based on the full-bridge LLC resonant circuit.This mathematical model is a high-order nonlinear system that needs to be approximated to obtain a usable spatial state equation.A dual closed-loop controller is designed for the DC power system according to the space state equation and the PI control principle.Finally,a double closed-loop simulation model of full-bridge LLC resonant converter is built on Simulink simulation platform,and the simulation results are analyzed.
