TI模拟电路讲义 Understanding and Optimizing Electromagnetic
Compatibility in Switchmode Power Supplies
Bob Mammano and Bruce Carsten
ABSTRACT
Electromagnetic noise issues have long been a concern with switching power supplies, as their high-
frequency switching of voltage and current generate higher order harmonics that have the potential to
cause interference with system operation. While international specifications and standardized testing
procedures have at least provided a greater understanding of the problems, optimum solutions must still
come from techniques that are applied during the design process. This topic attempts to describe the
more significant causes of EMI in power supplies and offer design techniques to m
