Modern electronic systems are becoming progressively denser with a high level of integration. This article will present some tried and true methods to reduce electromagnetic interference (EMI) levels in power-supply system designs. Designers must be aware of serious EMI setbacks when they’re in the late stages of the design phase, which could otherwise lead to excessive costs in money and time.
This article discusses how to improve EMI in terms of filter size and cost while reducing design time and complexity, especially in switch-mode power supplies (SMPS).
