The Growing Ecosystem for eGaN FET Power Conversion

In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has subsequently spurred a growth in te ecosystem of power electronics that support GaN-based designs.

Driving GaN Into The Fast Lane

Ask EPC’s chief executive, Alex Lidow, what the future holds for his GaN power device business, and automotive certification features prominently.

Recently delivering AEC Q101-qualified 80 V discrete transistors for LiDAR, 48V power distribution systems and other applications, the company’s latest enhancement-mode FETs deliver higher switching frequencies and efficiencies than silicon MOSFETs, in a smaller footprint. And this is just the beginning.

“We have more transistors as well as integrated circuits designed for LiDAR [sensors] and are proceeding with automotive certification here,” highlights Lidow. “LiDAR is under intense cost and performance pressure so integrating components and improving performance while lowering the cost is a big deal.”

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

1843

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.”

Written by:

Wireless charging promises a cord-free future, one that offers freedom from being tethered to the end of a charging cable. One company might have its finger on the pulse for this wirelessly powered future. Alexander Lidow is the CEO and founder of Efficient Power Conversion, a company looking to expand upon its namesake. EPC most notably displays how it wants to revolutionize wireless charging with a seemingly simple desktop.
