摘要
在高性能开关电源的设计过程中,要求建立变换器的准确数学模型。但直流变换器一般具有非线性、多模态、时变的特点,需要使用新方法对其进行研究。针对非隔离式直流变换器的工作情况,采用状态空间平均法建立了Boost变换电路的数学模型。然后基于Boost变换器的模型,利用Matlab软件进行仿真分析,验证了模型的正确性。
Abstract： In the design process of high performance switching power supply, an accurate mathematical model is required to be established. Since the DC-DC converter usually has characteristics of nonlinear, multi-model, timevarying, so it is necessary to use new methods to study it. In view of the situation of the non isolated DC-DC converter, state- space average method is applied to establish the mathematical model of Boost transform circuit. Then based on Boost converter model, Matlab software is used for simulation and analysis. The simulation results verify the correctness of the model.
