A novel numerical analysis to characterize and to visualize the resonance behavior in a long cable is proposed. The resonance-due maximum amplification, and the frequency and position to which the maximum occurs, are represented in function of the load connected to the cable terminal in a 3-D plot here denominated “resonance surface response.” This analysis is based on a white box modeling and allows the design of protective measures against the resonance phenomenon, such as filter design, protection against cross-talk, adequate voltage insulation choice, etc. One of these applications is exemplified: the design of an output filter for a power converter connected to a long cable, from which the results are compared to a classical design of the same filter to highlight the advantages and demonstrate the robustness of the proposed technique.

用于限制连接到电源转换器的长电缆中的谐振的稳健滤波器设计技术

提出了一种新颖的数值分析来表征和可视化长电缆中的共振行为。谐振引起的最大放大率以及出现最大值的频率和位置，以连接到电缆终端的负载的函数表示，在此处称为“谐振表面响应”的 3D 图中。该分析基于白盒建模，允许设计针对谐振现象的保护措施，例如滤波器设计、串扰保护、适当的电压绝缘选择等。这些应用之一是示例：设计一个用于连接到长电缆的电源转换器的输出滤波器，将结果与相同滤波器的经典设计进行比较，以突出优势并证明所提出技术的鲁棒性。
