RECOM Universal Half-bridge Reference Design for IGBT, SiC & GaN transistors

4 layer board of 3.55 x 2.36 inches (90.0 x 60.0 mm).
Shared on April 21st, 2018 23:02

This platform design can be used to compare the real-life performance of various high power IGBT, 1st/2nd generation SiC, GaN, MOSFET and Cascode switching technologies. As the gate driver and PCB layout is the same for every transistor type, engineers will be able to compare and contrast switching performances and make informed choices about the proper technology for their application.

Many thanks to RECOM Power for making this evaluation board available.
