摘　　要：DC--DC开关变换电路是一个时变的、非线性的动态系统,它的分析与设计一直是一个难题。通过数学推导阐述了状态空间平均法是平均法的一阶近似,并通过MATLAB软件进行典型升压变换器(boost converter)的电路模型和数学模型仿真对比,定量地讨论状态空间平均法模型的适用条件,说明状态空间平均法的本质,指出使用状态空间平均法时,一定要注意使用条件。DC--DC switching converter is a time-variant and non-linear dynamic system, and it is difficult to analyze and design. State space averaging was proven to be the first-order approximation of averaging method, and the waveforms of simulations of typical Boost converter circuit models and mathematic models were compared by MATLAB software, and the applicable conditions of state-space averaging principle were quantificationally discussed. This is the essence of state-space averaging principle. When using the state-space averaging principle, the applicable conditions should be paid attention to.
