Power conversion efficiency is a key growth driver in electronics but there is often a trade-off between density and efficiency.


Gain More Knowledge On GaN (Gallium Nitride) FETs By Asking Questions!


The Best Questions Win a $100 Shopping Cart!



Join us for a webinar on GaN FeTs where you will discover advantages and applications for using.  During the Q&A we will be awarding 5 shopping carts of $100 for the best questions asked.   The idea is to gain more knowledge on GaN by asking questions.   Nexperia will also be making product samples available which you can use to run your own experiments using GaN FETs!  Compound or III-V semiconductors, such as Gallium Nitride (GaN), often offer performance benefits compared to Silicon (Si). For example GaN is mechanically stable, has a wide bandgap with high heat capacity and comparable thermal conductivity. However, III-V semiconductors tend to be more costly to process. Growing thick GaN epitaxial layers on large diameter Si substrate is a recent breakthrough. It reduces costs per wafer to a competitive level for power applications and allows processing in existing 200 mm fabs.    James Lewis will join as a co-presenter to ask questions and provide color commentary.


Efficient power use is a key industrial challenge and a driver for innovation. For some applications power conversion efficiency and power density are critical for market adoption. Prime examples include the trend towards automotive electrification and the high-voltage communications and industrial infrastructure sectors. GaN FETs enable smaller, faster, cooler, lighter systems, with lower overall system cost. In this session, we will discuss how Nexperia GaN FETs enable high efficiency and robust designs while increasing power density and reducing system complexity.

Powering the IoT infrastructure


Providing us with the always on cloud connectivity, processing power and storage we demand takes a lot of power. Very efficient high-end power supplies , such as 80 PLUS Titanium rated PSUs, are needed to deliver the reduced power losses in industrial automation, data centres, and telecommunications infrastructure. That is why the improved density and efficient power conversion offered by GaN-on- Si is critical.


Electrification of the powertrain


With every gram of CO₂ exhaust being vital in today’s cars, it is driving the move to vehicle electrification. From hybrids through to full electric vehicles, electrification of the powertrain is expected to dominate power semiconductor market growth in the next two decades. The power density and efficiency of GaN-on-Si will play a leading role in this space, specifically for on-board-chargers (EV charging), DC/DC converters and motor drive traction inverters (xEV traction inverters).


Partnering with Ricardo to develop GaN-based EV inverter design


GaN FET technology leads to systems with greater efficiencies at lower costs. With improved thermal performance and simpler switching topologies, leading to greater range for electric vehicles. GaN is now on the brink of replacing silicon based IGBTs and SiC as the preferred technology for the traction inverters used in plug-in hybrids or full battery electric cars.



Nexperia’s current GAN FET products and development roadmap are focussed on delivering reliable products to support both automotive and IoT infrastructure applications. Our GaN process technology is based on our robust and proven production processes which now generates industry leading power GaN FETs.

Ilian Bonov is a Product Marketing Engineer who works with the Power GaN team at Nexperia in bringing the Nexperia cutting-edge GaN technology to market. After spending several years as Power MOSFET Application Engineer, where he was helping engineers, from different industries, to successfully design their power electronics solutions, Ilian knows that GaN is the game-changer in Power Electronics and more engineers need to hear about it and about the benefits it can bring. Ilian holds a bachelor’s degree in Electronics from The University of Manchester.

Back when James was in high school and had hair, he grabbed a soldering iron for the first time. Repairing a Heathkit training board immediately hooked him on electronics. Well, after the burns healed. His first hardware hack was changing the RC oscillator on his TI-85 calculator to make games, like Breakout, run at a reasonable speed. During the PS2 gaming era, he created UnitiBlue, a modular adapter to use classic console controllers with PC emulators. (Back then we said “classic,” not “retro.”)

Today James 3d prints, laser cuts, and solders together things that beep, blink, and fly. Known as the Bald Engineer, he writes engineering articles, makes Arduino tutorials, and rants about capacitor types. His YouTube channel, AddOhms, features simple animated tutorials to explain electronics to everyone.
