Cambridge GaN Devices moves to support industrial applications with higher power reference designs and demos

Cambridge GaN Devices (CGD), the fabless, clean-tech semiconductor company that develops energy-efficient GaN-based power devices that make greener electronics possible, is addressing higher power industrial applications with its ICeGaN™ technology which has already proved itself rugged, reliable and easy-to-use in high volume consumer devices. At the APEC 2024, IEEE Applied Power Electronics Conference and Exposition, the company is introducing new reference designs and showing demos which address the broad and diverse industrial market.

At APEC, visitors to the booth are able to see the progress that CGD is making to support both emerging and existing markets for GaN technology..

With a high power density of 23 W/in³, GGD’s 350 W PFC/LLC reference design has an average efficiency of 93%, and a no-load power consumption of 150 mW. The CrM Totem Pole PFC + Half-Bridge LLC PSU has been realised using CGD’s 650 V, 55 mΩ, H2 series ICeGaN technology, and delivers 20 V / 17.5 A output.

The result of a partnership deal struck last year with Neways Electronics, a 3 kW photo-voltaic inverter is used to boost the DC solar voltage to a stable DC link voltage. With a maximum efficiency of 99.22% due to zero-current switching, it is a perfect example of how CGD’s GaN HEMT structure is simple for engineers to use, since it employs a standard silicon controller from Analog Devices Inc.

ICeGaN has been employed by AGD Productions in its compact AGD DUET amplifier which is rated at 300W 4Ω. This is the first time the company has used a 100% GaN power transistor design for both the power stage and the amplifier.

Finally, the GaNext project, a consortium of 13 partners from three nations has delivered compact 1 kW intelligent power modules featuring integrated drive, voltage control and protection circuits using CGD’s ICeGaN.

About Cambridge GaN Devices

Cambridge GaN Devices (CGD) designs, develops and commercialises GaN transistors and ICs enabling a radical step change in energy efficiency and compactness. Our mission is to bring innovation into everyday life by delivering effortless energy-efficient GaN solutions. CGD’s ICeGaN™ technology is proven suitable for high volume production and the company is rapidly scaling up with manufacturing and customer partnerships in place. A fabless enterprise, CGD was spun out from Cambridge University, and its founders, CEO Dr Giorgia Longobardi and CTO Professor Florin Udrea, still retain strong links with the world-renowned High Voltage Microelectronics and Sensors group (HVMS) at the University. CGD’s ICeGaN HEMT technology is protected by a strong and constantly-growing IP portfolio which is a result of the company’s commitment to innovation. The technical and commercial expertise of the CGD team combined with an extensive track record in the power electronics market has been fundamental to the market acceptance of its proprietary technology.
