摘要: 为使电力系统控制保护平台在复杂电磁环境下不因高速电路信号质量问题而发生故障,以IGBT串联控制平台高速电路进行信号完整性分析,通过对印刷电路板(PCB)进行阻抗计算,分析过孔孔径、走线长度、线宽对信号完整性的影响,寻求布线参数下的最优解。试验结果表明:通过布线参数的优化,改善了高速电路信号质量,解决了系统因高速信号过冲振铃现象而发生系统故障问题。

Abstract: Signal integrity(SI) of high speed circuits of the control platform for IGBT series valve is analyzed. The PCB impedance calculation is performed to analyze the effects of through hole radius, wiring length and width on signal integrity. The optimized parameters are found after calculation. The experimental results show that it is beneficial to improve the signal quality by optimizing routing parameters. Potential system failure for high speed signal overshoot and ringing phenomenon is also avoided.

Key words: signal integrity, high-speed circuit, analysis and design, controller platform, optimal design, routing, impedance
