Alex LidowThis scientist got his Ph.D 40 years ago who saved the world’s 15% energy consumption at one time. He is continuing his journey of innovations now in discovering silicon’s replacement material for humankind.

My father always taught me that the true worth of an individual is measured based on their contribution to society. As I entered graduate school in 1975 I knew my passion was in the field of semiconductors, and I felt my best contribution to society would come from finding a successor to silicon. I did my graduate work in Gallium Arsenide, but realized by the time I received my PhD in 1977 that Gallium Arsenide’s prospects were limited as a semiconductor due to the basic materials properties, I went to work applying everything I learned to making better devices in silicon.

Fact: GaN technology a more efficient semiconductor than silicon for the Data Center power conversion process.

Written by:

Over the past few decades, metal oxide semiconductor field effect transistors (MOSFETs) have largely been the staple source for power supplies. MOSFETs are silicon-made devices controlled by voltage that manipulate the supply’s electricity that come in the form of little black squares. They’ve become very prevalent throughout the semiconductor industry, but might see their mainstream status begin to wither.

Emerging the scene is gallium nitride (GaN), devices that are expected to become smaller, cheaper, and more efficient in the long run. Silicon-based semiconductors had voltage coming into a data center at 48V go through multiple instances of power conversion before finally reaching its on-board components, during which the voltage would shed energy at each of these phases. According to Dr. Alex Lidow, chief executive of the Efficient Power Conversion (EPC) Corporation, Silicon wasn’t fast enough to reach 1V all the way from 48V.

“So what we (as an industry) did was create a whole bunch of very expensive power supplies that get you from 48V to 12V, and another set of power supplies that get you from 12V to 1V,” says Lidow.  “And with gallium nitride, since it’s so damn fast, you can get rid of the whole intermediate bus and go directly from 48V to 1V.”
