摘　　要：为提高矿井电机车三电平结构照明电源的控制性能,根据矿井电机车照明开关电源的特点,以BUCK三电平结构为主的工作模式,建立电源系统控制的数学模型。仿真结果表明:稳态运行时,抑制纹波的效果良好。该方法调试简单,为闭环系统的设计提供了参考。In order to improve the performance of three - level mine electric locomotives lighting power supply, according to the characteristics of the light switch power supply, BUCK three - level was used to be the main operating mode, and established the mathematical mode of the power system. The simulation results confirmed that the current ripple be well suppressed when running under the steady- state and also the debug is simple. The proposed scheme can be extended and applied to close - loop system.
