WHERE ARE THE HIGH VOLTAGE GAN PRODUCTS?

I will go over what we have seen in GaN so far... Like: We are seeing introductions of low voltage GaN and some experimental devices at the 20 V level somewhat stated to be 200 V. However, I will point out that GaN is essentially a high voltage technology and could possibly leverage itself to be dominant at high voltage. There are many in the industry who have great expectations for high voltage GaN (rated from 500 V to 1200 V and later going to 1700 V). The article also includes comments from Dr. Alex Lidow of EPC and Tim McDonald of International Rectifier. ...
