摘要
讨论了动力蓄电池组测试系统低纹波快速响应滤波器的设计和参数选取方法,达到了限制滤波器暂态谐振峰值,提高响应速度和保证稳态滤波效果的目的。在详细分析元件损耗对滤波器特性影响的基础上,提出利用网络局部元件的耗散因数调整滤波器传输函数的归一化零极点位置,有条件地使其左偏移,从而有效地抑制暂态谐振峰值,并提高滤波器响应速度。提出简化的切比雪夫直流滤波器阶数的计算方法。仿真和实验结果表明该滤波器设计方法可以达到低谐振峰值,快速响应以及稳态滤波效果好等目标。
Design and preferences of the low ripple and fast response filter are discussed, which can restrict the resonance peak value, accelerate the transfer speed and maintain the steady filtering consequence. The influence of partial element decay on the filter＇s transfer characteristic was analyzed and a design method was presented to enhance the filter＇s transfer speed. Appropriate partial component dissipation was adopted and the decay pole near the harmonics frequency was made to achieve reasonable filtering result. A way to determine the order of Chehyshev DC filter was presented. Simulations and tests results prove that the filter possesses merits of low resonance value, fast converse ability and excellent filtering effect.
