摘　　要：由于Boost变换器是一个非线性时变系统,用解析方法进行动态分析较为复杂,所以采用了状态空间平均法建立了主电路的小信号模型。采用Pspice仿真分析方法,对Boost电路的工作过程和升压原理进行了详细的分析,给出了直观易懂的计算机仿真结果,验证分析的正确性,对深入理解Boost电路有极大的促进作用。Because Boost converters are a nonlinear time-varying system, it is very complex to use an analysis method to make dynamic analysis. So the small signal model of the main circuit is built by state space average method. Use pspice artificial analysis method to analyze the operation process and the boost principle of the Boost circuit in detail. It gives out visible and easy to understand computer simulation result, which verifies analysis correctness. It is of great facilitation to under stand Boost circuit deeply.
