APEC in San Antonio: Texas gets the power family together again. It is always a great opportunity in March for a nice warm place to work, and moving important information out to engineers who will develop the more efficient designs of the future.

With wide band gap devices we have new challenges – getting the packaging right and the passive components to match the speed and thermal performance of GaN and SiC devices. All manufactures of power semiconductors are facing up to the challenge of SiC and or GaN. We see GaN now up to a kilovolt or a little above. SiC is capable of several kilovolts for applications that require high voltage. The future is in improved efficiency over previous designs. Products have become mature and applications are running at end users.

Wide Band Gap devices have paved a road to our future designs. We are now in a phase of adoption that requires a wider group of engineers to get familiar with wide band gap devices for their new designs. Higher switching speed, potentially higher temperature, and lower losses present challenges: for passive components, for the measurement of signals, and for switching interference. APEC in San Antonio is a place for experts to present their latest developments. We will be present with our team to get you up to date with their progress.

It is important that we have enough power to speak out for freedom in the world.
I still look forward to see fair treatment of journalists in the world. It is not acceptable that journalists be held in jail, without any accusation, for a full year. Too bad if their reports are critical of what they see. We have to work for the freedom for Deniz Yücel. Journalism keeps freedom alive for us all – there are innumerable examples from our past to teach us.

My Green Power Tip for March:
If it is cold outside and freezing, wear an extra pullover. You will be able to do more walking in wintertime.
