基于状态空间平均法的非理想buck变换器CCM模态建模与仿真

Modeling and simulation of non-ideal buck converter in CCM mode based on state-space averaging method

精确数学模型是变换器设计、研究的基础,是观察、控制变换器输出特性的前提条件.本文采用状态空间平均法对非理想型buck变换器进行建模,得到其精确数学模型,并通过对matlab/simulink中buck变换器电路仿真验证基于状态空间平均法建模的正确性.

Accurate mathematical model is the basis of converter design and research,the prerequisite of the observation and control of the inverter output characteristic.In this paper,the state space average method is adopted to non-ideal buck converter modeling,getting its accurate mathematics model.And simulating based the buck converter circuit method on the matlab/simulink to verify the correctness of modeling based on state space average.
