摘要

相比于常规的高压直流电源,脉冲激励型静电除尘电源利用直流高压叠加窄脉冲的方式对粉尘进行荷电,具有易清除高比电阻粉尘、有效抑制反电晕、不易发生闪络、效率高等优点。在此对高压开关型脉冲静电除尘电源进行研究,分析电源的电路拓扑与工作原理,建立电路的数学模型并分析,并通过仿真软件分析系统参数对电源性能的影响,最后通过搭建1.45 kV小型脉冲电源系统进行实验验证。
        Compared to the conventional high voltage direct current power supply,the pulse power supply for electrostatic precipitator is charged to the dust in the form of high voltage superposition and narrow pulse.It is easy to remove the high specific resistance dust,effectively suppress the back corona,not easy to flashover and high efficiency.The high voltage switch pulse electrostatic dusting power supply is studied,the circuit topology and working principle of the power supply are analyzed,the mathematical model of the circuit is established and analyzed.Finally,the experimental verification is carried out by building a 1.45 kV small pulse power supply system.
