Engineering Tomorrow:
GaN, SiC, and the

Future of Sustainable

Energy Systems Signal

Gallium nitride has moved from niche to mainstream in just a few years. Once Processing
limited to niche applications such as fast chargers, GaN now powers data centers, in Embedded
solar inverters, and electric-mobility systems. Eric Persson, senior principal engineer,
and Paul Wiener, strategic marketer, both at Infineon Technologies, explore how GaN System
has evolved from niche to mainstream and why Infineon’s CoolGaN stands out in
both high- and medium-voltage domains. Readers can expect insights into device
structures and gate robustness but also a look at Infineon’s IDM manufacturing
leadership and 300-mm wafer roadmap.
The electronics industry today stands at the intersection of powerful forces: the

Meanwhile, IoT systems for smart buildings and homes are revolutionizing how
energy is consumed and conserved, offering measurable reductions in the carbon
footprint of residential and commercial infrastructure. Yet the proliferation of
battery-powered IoT devices presents an environmental paradox: mounting
e-waste. Advances in energy-harvesting technologies, as emphasized by e-peas’s Signal Processing in
Bruno Damien, offer a path forward: self-sustaining IoT devices that not only reduce Embedded Systems

But systemic change doesn’t come from established players alone. Startups
remain the accelerators of transformation. Sweden exemplifies how ecosystems
uniting academia, government, and industry can yield global impact. The story
of Hexagem, a spinout from Lund University leveraging decades of research in
III-nitride epitaxy, shows how deep science can be harnessed for breakthroughs in
both power electronics and microLED displays. On the other side of the Atlantic, Smart Building Management
