摘要
研究了直流升压变换器动态响应特性。运用小信号的分析方法建立了直流升压变换器的动态模型,分析了系统的动态响应时间与各个器件之间的关系,计算了升压变换器反馈控制回路的补偿函数,从而提高变换器的静态性能和动态性能。仿真分析和实验研究验证了该动态模型的合理性。
The dynamic response characteristics of DC Boost converter were researched. Based on little signal method, the dynamic model of DC Boost converter was founded, and the relation between dynamic response time of system and devices was analyzed. The compensation function of converter feedback control loop was reckoned to improve static and dynamic characteristics of converter. The rationality of dynamic model was testified by simulation and test.
