PSDwebinar: Minimizing EMI and Switching Loss for Fast SiC FETs
Hosted by Power Systems Design, sponsored by United SiC Inc.
Join this webinar to discover how a simple RC snubber can effectively control turn-off VDS spike and ringing of SiC devices and “surprisingly” being more efficient than just using high Rgoff. The snubber resistor loss is also much smaller than conventional calculation which allows the use of SMD resistors. Waveforms and switching loss will demonstrate the excellent performance of SiC devices with a small RC snubber. Moreover, using snubber even improved the dual compatibility of fast SiC devices. The scope of the discussion will include the following:
• Turn-off VDS spike with fast SiC devices
• Root cause and viable solutions
• Snubber vs Rgoff
• Effectiveness
• Switching Loss
