摘　　要：在静电除尘应用中,与常规的高压直流电源相比,脉冲电源可降低能耗并能大幅提高微细粉尘的脱除效率,微秒级的电压宽度可以有效抑制反电晕并且不易发生闪络。对一种串联对称式脉冲静电除尘电源进行研究,分析电路的稳态工作原理和闪络工作情况,建立电路的数学模型并完成电源输出特性研究,最后通过仿真和100 kV脉冲电源样机进行验证。In electrostatic precipitator applications,compared with conventional high-voltage DC power supplies,pulse power supplies can reduce energy consumption and greatly increase the removal efficiency of fine dust.The microsecond voltage width can effectively suppress back corona and is less prone to flashover.Research on a series symmetrical pulse electrostatic precipitator power supply,the steady-state working principle and flashover operation of the circuit are analyzed,the mathematical model of the circuit is establishd and the power output characteristics research is completed.Finally,it is verified through simulation and a 100 kV pulse power supply prototype.
