PowerAmerica: Accelerating The Next Generation Of Wide-Bandgap Power Electronics
and more…
Collaborations between industry and academia help to propel new technologies forward. There are many examples of this in power electronics with universities having their own industry consortia to support their research programs. Then there are organizations working at a higher level to advance technology by supporting and coordinating the efforts of many companies and research institutions. PowerAmerica is one such group. This consortium of almost 50 organizations from industry and academia is working to speed up acceptance of SiC and GaN power devices in the marketplace. You can read about the R&D projects they have funded and the educational and training programs they offer in this month’s Spotlight on Education and Research. In the past when silicon power MOSFETs and IGBTs… Read more»
Saving Face American Style: Engineering Integrity Can Be Detrimental In Post-Global Business Culture
by Paul L. Schimel, PE
A dear friend wrote to me about an interview he’d had for an FAE position at a big power semiconductor company. It started out with an urgent call from a senior staff sales engineer. But as my friend told the interviewer about the deep skills and experience he would bring to serving the customer, it became apparent that such abilities would not be considered assets in a business where sales booked per quarter were all that mattered.

POWER INTEGRITY INSIGHTS
The subject of power integrity (PI) concerns the design, analysis and testing of components and systems for the purpose of accurate and reliable delivery of voltage and current from the voltage regulators across power distribution networks (PDNs) to complex and sensitive loads in electronic systems. The challenges of designing modern, high-speed electronic systems are making it increasingly important for engineers to understand PI.
