A lot of engineers don’t have a good feel for how gallium-nitride FETs perform compared to silicon-carbide equivalents. So GaN Systems devised two 650-V, 15-A switching supplies using SiC and GaN to see how they compared. In an interview conducted by WTWH Media’s Lee Teschler, Jim Witham explains the differences that emerged in this head-to-head…
In this episode of PSDtv from PCIM Europe 2017, Jim Witham, CEO of GaN Systems discusses benefits of wired and wireless charging using GaN transistors. Jim discusses a wired charger for notebook computers that generates a power density of 35 W/cubic inch…which is 3x the normal charger power density. Also shown is a wireless charger…
This video, originally published on Electronics Products Magazine’s YouTube channel, was recorded at PCIM 2017. GaN Systems’ CEO, Jim Witham, talks with Alix Paultre about the adoption of GaN technology and describes some of the 30+ customer products displayed at PCIM that are performance-optimized by GaN transistors.

Charge pads can now charge multiple wireless devices simultaneously thanks to gallium-nitride FETs. In this short demo, WTWH Media’s Lee Teschler interviews GaN Systems’ Jim Witham who described a 70-W charging pad built by Gill Electronics to the AirFuel standard that has a two-inch throw. This feat is made possible only through the use of…
This video was produced by Aspencore and posted to Electronics Know-how. Power system companies continue adopting gallium nitride (GaN) transistors in place of silicon IGBTs and MOSFETs. By designing GaN into power systems and modules, customers have launched a stream of smaller, lighter and less costly electronic systems into the market. These products exhibit dramatic…
In this episode of PSDtv, originally recorded by Alix Paultre, CEO Jim Witham takes us through GaN Systems’ booth at electronica 2016, held in Munich, Germany this past November. Mr. Witham describes our latest advances and shows examples of how customers are using our latest GaN transistor products in their power systems. Watch on YouTube…
The auto industry is poised to begin a shift from silicon chips to smaller and more efficient “wide-bandgap” semiconductors made with gallium nitride, says Karina Morley, Ricardo’s commercial director, Automotive. These advanced chips will be 20%-50% smaller than the silicon semiconductors they replace. That will enable far more compact electronic control modules. Gallium nitride chips…
In this video the CE+T team describes the challenges they confronted and how they used GaN Systems transistors to develop the inverter that won Google and IEEE Little Box Challenge.
Hey, Teschler, EGTRONICS Shrunk the Inverter! GaN transistors are here, they’re now and they’re proliferating in production designs. As just one example, in this video which was filmed at APEC 2016, GaN Systems’ President, Girvan Patterson, describes to Design World / EEWorld’s Lee Teschler the impact that GaN transistors have had on EGTRONICS’ production model…
GaN Systems’ Di Chen explains how to test 650 V GaN transistors for your application. Our eval board is easily configured into any half-bridge-based topology, including synchronous boost and buck conversion modes, as well as pulsed switching to evaluate transistor waveforms.
