EMI debugging of embedded power electronics designs

EMI debugging of embedded power electronics designs

Locate, capture and analyze EMI problems quickly & accurately

Electronic products have to meet EMC standards before they can be launched on the market. DC-DC converters in embedded designs are often a source of unwanted conducted or radiated emissions. Noncompliance typically means time-consuming debugging. Prompt analysis of EMI problems during development is a key success factor for launching products on time. The powerful spectrum analysis capabilities of Rohde & Schwarz oscilloscopes allow developers to debug EMI problems when designing embedded devices.

Optimizing wide-bandgap semiconductor switches to meet EMI compliance

EMI compliance will become a major concern for next-generation power electronics due to their increasing switching speeds. Correlated measurements in the time- and frequency domain help to improve gate driving and minimize electromagnetic emission already during power electronics development.

Video: How to EMI debug

Oscilloscopes have become powerful tools for troubleshooting EMI issues at the engineers desk. This video shows how the R&S RTO oscilloscope can be used with a near-field probe to quickly and reliably locate and resolve EMI issues during development in the R&D lab. This can effectively minimize expensive re-testing and shorten the time to market.
