摘　　要：根据DC/DC变换器的基本原理,基于VISSIM建立了BUCK变换器的仿真模型,采用双滑模面控制方法,内环滑模面用于电流控制环,外环滑模面用于电压控制环,并将仿真结果与PI控制方式相比较。仿真结果表明了滑模控制的优越性,为研究BUCK变换器的滑模控制提供了新方法,也为进一步研究其它DC/DC变换器的滑模控制提供了新思路。A BUCK converter＇s model was established based on VISSIM according to the basic principles of the DC/DC converter. Then a double sliding surface control method was proposed, the inner sliding surface was for the current control ring while the outer sliding surface was for the voltage control ring. After that, the simulation results was compared with PI control method. The simulation results showed the superiority of the sliding control, it not only provided a new way for the research of the slide mode control for the BUCK converter,but also gave a new thought for the research of the slide mode control for the other DC/DC converters.
