摘　　要：DC-DC变换器广泛应用于通讯、计算机、工业设备和家用电器等领域。对其仿真具有重要的意义。然而在使用传统电路仿真软件对其进行电路仿真时,实际情况并不理想,且仿真速度也相当慢。Matlab/Simulink作为国际上较为流行的用来对动态系统进行建模、仿真与分析的软件包,在对DC-DC变换器电路进行仿真时显现出巨大优势。通过对Buck变换器开关过程的分析,应用Matlab/Simulink的3种方法对其进行仿真。最后通过仿真波形进行比较,其结果是一致,且与理论相符。可见Matlab/Simulink适合于在DC-DC变换器仿真中应用。应用Matlab/Simulink对DC-DC变换器进行仿真是一次创新,其大大提高了仿真效率。DC- DC converter is widely used in communication,computers,industrial equipment and household appliances. Therefore its simulation is of most importance. However when the traditional simulation soft wares are used in the simulation of DC- DC converter,the simulation circumstance is not perfect in fact and the simulation speed is very slow. Matlab/Simulink is a soft ware used popularly in the modeling,simulation and analyzing of dynamic system internationally. It also shows much advantage when used in the simulation of DC -DC converter. By analyzing the switching process of buck converter,its simulation is finished with three methods of Matlab/Simulink. At last,the simulation results are consistent and correspond to theory by comparing the waveforms of simulation results. Obviously,Matlab/Simulink is suitable for the simulation of DC - DC con- verter. The application of Matlab/Simulink in the simulation of DC -DC converter is an innovation, which greatly improves the efficiency of the simulation.
