摘要
为了辅助升压变换器(Boost变换器)在应用中的设计,分析了电流断续状态下Boost变换器的工作过程,建立了这种状态下的Boost变换器非线性数学模型,在结合二进制逻辑变量,建立了S im u link模块下的变换器仿真模型,研究表明仿真结果与理论分析结果一致,证实了模型的准确性和可行性,这种逻辑与模拟结合的简明通用的模型可以高效辅助Boost电路设计并为参数优选打下了基础。
In order to assist Boost converter design, the working process of the converter at discontinuous current mode was analyzed and a nonlinear mathematical model was estabilished as well. Case study on Matlab/Simulink was performed with binary logical variable used,the simulation result was consistent with the theoretical analysis which proveed the validitd and feasibility of the proposed model. The model could be used to assist Boost circuit design effectively and supplie a basis for parameter optimization.
