Wolfspeed C3M SiC MOSFET's require a gate drive voltage of +15V/-4V which can be generated using several different methods. An Application Note that discusses the various techniques along with the pro's and cons's of each will be available on Wolfspeed.com soon. Some additional notes on the methods is below :
- An off-the-shelf isolated DC/DC power supply from Murata, Mornsun or Recom is the simplest way to generate the required bias.The Wolfspeed evaluation board CGD15SG00D2 demonstrates application of the the Murata module MEJ2D1209SC for generation of +15V/-3V gate drive voltage.
- A discrete design can provide a more cost effective solution, flexible and smaller form factor at a low cost. One example can be found in the Texas Instruments reference design - TIDUE55B .
