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® Technology.
