Electromagnetic susceptibility analysis of 32 bit digital signal controller
-
摘要: 研究了传导电磁干扰下，数字信号控制器的电磁抗扰性能预测与分析。针对一种典型32位数字信号控制器，设计了基于直接功率注入法的敏感度测试平台，测试得到了敏感度阈值；并通过S参数测量、输入输出缓冲器信息规范（IBIS）参数提取，建立了集总参数的电磁敏感度仿真预测模型。模型仿真结果与测试结果在10 MHz到1 GHz内具有较好的一致性。Abstract: In this paper, an electromagnetic compatibility (EMC) conducted immunity model of a 32 bit digital signal controller (DSC) is presented. The immunity model predicts the susceptibility behavior of a complex microcontroller to conducted disturbances injected through an input buffer. Two major parts of the model, the injection path and power distribution network of input buffers, are detailed according to S-parameter measurement, input output buffer information specification (IBIS) file and non-confidential information. The susceptibility level of the digital signal controller is measured using the direct power injection (DPI) method, and a good agreement between measurements and simulated results is reported in the frequency range from 10 MHz to 1 GHz.
