说明：  boost变换器是一种DCDC升压装置，使用及其广泛，而且性能稳定。该matlab仿真模型是电压模式控制下的boost变换器模型，保持输出电压稳定。该模型应用simulink仿真。效果挺好。
(Boost converter is a kind of DCDC booster device, use and wide, and stable performance. The matlab simulation model is under the control of voltage mode boost converter model, keep the output voltage stability. )
