How to Reduce EMI in Switch-Mode Power Supplies with Post-Layout Simulation

The need for greater efficiency, increased power density, and lower cost is driving the demand for high-speed switch-mode power supplies (SMPS). This trend results in new challenges, as the layout of a printed circuit board becomes a source of electromagnetic interference (EMI). Post-layout analysis of a “virtual prototype” is ideal for managing this challenge, but until now it required expertise with a complicated, general-purpose electromagnetic field solver. In this webinar, we show how Keysight’s PEPro software makes post-layout analysis as easy as pre-layout analysis.
- A higher-speed SMPS is smaller, lighter, and cheaper, but higher speeds introduce new challenges, such as unwanted EMI
- Suppression of EMI by traditional “solder-and-see” methods is costly, time-consuming, and nondeterministic
- In this webinar, we present a new method that is cost-effective, is faster and yields deeper insights — namely a series of “virtual prototypes” using post-layout simulation
