This webpage introduces technical papers that describe the outcomes of the OMRON Group’s R&D activities, as well as the technologies that support its products and services.
Recently, high-speed switching circuits using GaN GIT have attracted attention for higher power density. In particular, GaN GIT devices have an ultrafast speed capability but tend to cause false turn-ons due to a lower threshold voltage. A simple RC-type gate drive method is usually used to prevent the false turn-on phenomenon....
