Validating Efficiency and EMC on WBG devices

Validating Efficiency and EMC on WBG devices

ROHDE & SCHWARZ WEBINAR joined with Würth Elektronik

Wednesday, March 19, 2025 at 14:00 CET

Are you developing switched mode power supplies? Do you want to switch from traditional silicon to wideband gap devices made of SiC or GaN and wonder how this will improve your efficiency and how EMC is affected? Then join us in this webinar to see which losses are affected by the used material and what to keep in mind when performing measurements on such devices.

This Webinar will handle the following topics:

• Why use GaN instead of Silicon? Here the material characteristics will be discussed and a loss analysis of a buck converter will be performed.
• What to know when designing your SMPS with a GaN device and how to provide measurements points and select the right passives.
• How to select the right oscilloscope and probing solutions for your application.
• How and why to isolate your oscilloscope from your DUT to measure signals like high-side gate or a current. Is really always an optical isolated probe needed?

Don’t miss this chance to learn more on how to best handle the trending materials like SiC and GaN in your daily work. Reserve your spot now!

In this webinar, you will learn more about:

• Advantages of GaN over Silicon: Understand the material characteristics and how GaN improves efficiency in power supply design.
• Loss Analysis in a Buck Converter: Learn which losses are influenced by switching from silicon to GaN.
• SMPS Design Considerations: Key factors to keep in mind when designing switched-mode power supplies (SMPS) with GaN, including measurement points and passive component selection.
• Oscilloscope and Probing Selection: Guidance on choosing the right oscilloscope and probes for accurate measurements.
• Isolation Techniques for Measurement: Learn when and why you need to isolate your oscilloscope, including alternatives to optically isolated probes.
