SiC vs GaN Head-to-Head Performance Comparison

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…

PSDtv – GaN Systems on Customer’s Applications of GaN Transistors

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…

Wireless Charging Using 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…

How GaN Enhancement-mode HEMT devices improve the performance of Power Systems

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…

Ricardo Discusses Using GaN Transistors in Automotive Systems

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…

CE+T Power – The Little Box Challenge Adventure

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.

EGTRONICS 48V, 12 kW Inverter

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…

Getting started with the GS66508T-EVBHB 650 V half bridge evaluation board

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.
