基于VISSIM的DC-DC变换器建模与仿真研究

根据DC-DC变换的基本原理，在连续导通模式下，基于VISSIM对BUCK、BOOST、BUCK/BOOST三种变换电路分别构建了仿真模型，仿真结果与理论分析的一致性表明了建模方法的正确性。提出的模型适合于验证不同DC-DC变换电路的运行特性、控制算法，为分析设计DC-DC变换电路及其控制系统提供了有效的方法，同时也为实际电路的设计调试提供了新思路。

Modeling and Simulation of DC-DC Converter Based on VISSIM

According to the principle of the DC-DC converter, the comparison and analysis of three sorts of commutation circuits, namely BUCK, BOOST and BUCK/BOOST were dealt with, and of which the modeling was also investigated in continuous mode, The simulation results in VISSIM are consistent to the theoretical analysis and show the effectiveness of the modeling method. These proposed models have great significance in testing the performances and control algorithm for different kinds of DC--DC converters. Based on these models, an efficient way for analysis and design of the DC--DC converter circuits was provided, while a novel approach for designing and debugging actual circuits was also given.
