| 摘要: |
| 根据DC/DC变换的基本原理,在断续导通模式下,依据状态空间法建立了BUCK、BOOST、BUCK/BOOST 3种变换器的数学模型,并在此基础上基于VISSIM对3种变换电路分别构建了仿真模型进行仿真。利用该仿真模型不仅可以有效模拟实际的DC/DC变换电路的运行特性,可采用不同的控制算法、控制策略对该模型进行闭环控制,还可通过VISSIM软件与C 、DSP和集成的Matlab模块连接,从而不仅为分析设计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。仿真结果与理论分析一致,表明了建模方法的正确性。 |

| Abstract: |
| According to the principle of DC/DC converter,the math models are established for BUCK,BOOST and BUCK/BOOST converters under DCM(Discontinuous Conduct Mode) using state space method,based on which the corresponding simulation models are constructed with VISSIM.The characteristics of actual DC/DC converters are effectively simulated,applying different algorithms and strategies of closed-loop control.The models can connect with the C ,DSP and Matlab modules via VISSIM,offering an efficient way to DC/DC converter design and actual circuit test.Simulation results accord with theoretical analysis,showing the validity of proposed modeling method. |
