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…
OTTAWA, Ontario – October 2, 2017 – The world is challenged with unsustainable increases in power consumption, combating climate change, implementing cleantech technologies and meeting green, CO2 reduction initiatives. Taiwanese electronics manufacturers work at the forefront of these efforts. To meet these challenges, GaN Systems, the world’s leading provider of gallium nitride (GaN) power transistors,…
The following article, written by Mathew Dirjish, originally appeared in Sensors Online. Silicon has been the mainstay of semiconductor fabrication for as long as one can remember. It is the meat of transistors, OP amps, microprocessors, MCUs, PLCs, and numerous other devices. The material has proven more than viable and reliable and will be with…

Kanata company’s next-generation semiconductor technology attracts multimillion-dollar injection of equity led by German automaker A Kanata firm that makes transistors that help electric and autonomous vehicles run more efficiently has landed millions in funding from one…
Engineers gain a head-start and design accuracy OTTAWA, Ontario, August 15, 2017 – Power system design engineers want to be fast, accurate and confident with their simulated designs prior to building hardware. Achieving these goals with GaN designs has become easier with GaN Systems’ new set of LTSpice models. Increasing efficiency and power density requires…
Mountain View – July 18, 2017 – GaN Systems, the world’s leading provider of GaN power transistors, announced the closing of an investment round led by BMW’s investment arm, BMW i Ventures. Consistent with its investment strategy, BMW i Ventures recognizes that GaN Systems’ products maximize the efficiency of electronic systems while dramatically reducing size,…
This article was originally published in the June 2017 issue of Bodo’s Power Systems. Research on wide bandgap (WBG) devices has been conducted for many years. The reason that the properties of Gallium Nitride (GaN) and Silicon Carbide (SiC) excite power engineers is because they show substantial performance improvements over their silicon-based counterparts. By Jason…
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.

This article was written by Sam Davis and first appeared in powerelectronics.com Paralleling GaN transistors increases the power handling capability of a high-efficiency and high-power density converter. To be successful, parallel operation depends on the designer’s ability to deal with parasitic elements within the GaN devices as well as those associated with interfacing circuits. Characteristics…
GaN Systems releases industry’s first E-HEMT bridgeless-totem-pole Power Factor Correction reference design OTTAWA, Ontario, May 9, 2017 – Achieving efficiencies greater than 98% in conventional Power Factor Correction (PFC) circuits is challenging. The major hurdle is fixed diode bridge losses. An option to overcome this is to use silicon MOSFETs in place of the diodes…
