针对电压电流双环反馈控制的电感电流连续型Boost变换器模型,在一定参数范围内利用数值分析和MATLAB仿真方法研究了电感、电流反馈系数和输出电压3个参数对Boost变换器工作状态的影响.研究表明,在特定参数下数值分析与系统分岔图所反映的系统特性一致.

For the inductor current continuous Boost converter model with voltage and current double loop feedback control,the influence of three parameters of inductance,current feedback coefficient and output voltage on the working state of Boost converter is studied by numerical analysis and MATLAB simulation in a certain parameter range.The results show that the numerical analysis is consistent with the system characteristics reflected in the system bifurcation diagram under the specific parameters.
