摘要
简要介绍了CRH3型动车组辅助供电系统的组成。选用合适的控制方法,利用MATLAB对其核心部件——单变流器和双变流器进行建模仿真,根据仿真结果对系统输出电压的波形、有效值进行分析评价。最后改变相应参数,模拟了动车组在实际运行过程中输入电压的波动对变流器输出的影响。
This paper briefly introduces the auxiliary power supply system of CRH3 EMUs, and establishes the simulation models of single converter and double converters by MATLAB, then analyzes and evaluates the waveform of the output voltage and the effective value of the output voltage based on the simulation results. Finally, by changing the corresponding parameters, the influence of the fluctuation of the input voltage on the output of the converters is simulated.
