[WEBINAR] Minimizing EMI and switching loss for fast SiC FETs

Hosted by Power Systems Design, sponsored by UnitedSiC Inc.

 

ON DEMAND

 

Join this webinar to discover how a simple RC snubber can effectively control turn-off VDS spikes and ringing of SiC devices and be “surprisingly” more efficient than using a high Rgoff resistor.  Also, we’ll show how the snubber resistor loss can be much smaller than the conventional calculation, therefore allowing the use of SMD resistors.  Waveforms and switching loss data will demonstrate the excellent performance of SiC devices with a small RC snubber.  Finally, we will show how using a snubber can improve the dual compatibility of fast SiC devices.

  • Snubber vs Rgoff
    • Effectiveness
