Abstract

The goal of DC power filtering is to provide stable DC power and reduce electromagnetic interference (EMI) and transients. As integrated circuits (IC) on printed circuit boards (PCB) increase in power demands, have faster switching frequencies and larger population densities, power filtering gains in cost, complexity, and frequency range. The paper highlights the radiated emissions results of a microprocessor development board using different combinations and configurations of power filters and evaluating it against the X2Y/sup /spl reg// Technology.
一种更好的直流电源滤波方法
直流电源滤波的目标是提供稳定的直流电源,减少电磁干扰和瞬变。随着印刷电路板(PCB)上的集成电路(IC)功率需求的增加,开关频率更快,人口密度更大,功率滤波的成本、复杂性和频率范围都在增加。本文重点介绍了一种微处理器开发板使用不同电源滤波器组合和配置的辐射发射结果,并对X2Y/sup /spl reg//技术进行了评估。
