资料介绍

针对测试系统在给某大功率滤波电路加阶跃电压后形成欠阻尼振荡电路,产生正向、反向大电流,造成测试时的欠电压、过电压干扰现象,进行了详细机理分析,提出了增加过阻尼电路预加电的改进方法。同时通过理论分析和试验验证,证明了改进的有效性,确定了改进的具体参数。

This paper analyzed the transient under-voltage and over-voltage interference occurrence during the test of a high-power filter circuit. Underdamped oscillation circuit is formed,and the forward and reverse high current is generated when the test system applies step voltage to the high-power circuit. Then,under-voltage and over-voltage interferences are caused. To solve the problems of the original test system circuit,an improved method,by which the power is pre-supplied in the damping circuit,was proposed. The effectiveness of this improvement is proved,and the optimized parameters are determined by the theoretical analysis and experimental verification.
