摘　　要：提出了一种浪涌电流抑制电路参数设计的方法,并对使用该方法设计的浪涌电流抑制电路进行了实验测试。首先,通过构建RC并联结构的浪涌电流模拟源替代真实测试设备,用于浪涌抑制电路参数的设计以及测试,浪涌电流模拟源的参数通过计算、仿真得到;然后确定浪涌抑制电路结构,通过仿真不同参数的浪涌抑制电路对浪涌电流模拟源的抑制情况,设计浪涌抑制电路的主要参数。搭建实际的浪涌抑制电路及浪涌电流模拟源进行实测实验,实验结果表明,通过该方法设计的浪涌抑制电路可将浪涌电流模拟源的浪涌电流从95A抑制到7.5A,浪涌电流产生的时间延迟了700μs左右,满足项目中对浪涌电流幅度不得超过10A的要求。A method for designing the parameters of inrush suppression circuit is proposed and the inrush suppression circuit designed by this method is tested experimentally.Firstly,the simulated inrush source with RC parallel is constructed to replace the real test equipment for the design and test of the circuit parameter of the suppression.The parameter of simulated inrush source are obtained through calculation and simulation.Then,Determine the structure of the inrush suppression circuit,and the main parameters of the inrush suppression circuit are designed according to the desired suppression effect by simulating the suppression of the inrush suppression circuit with different parameters on the simulated inrush source.An actual inrush suppression circuit and A simulated inrush current source were set up for the field test.The experiment showed that the inrush suppression circuit designed by this method could suppress the inrush current of the simulated inrush current source from 95A to 7.5A,The timing of the inrush was delayed by about 700μs,meeting the requirment of the project that the inrush amplitude should not exceed 10A.
