Cambridge GaN Devices: Revolutionizing Power Electronics with MOSFET Technology

Cambridge GaN Devices is revolutionizing the landscape of higher power industrial applications with its innovative ICeGaN technology. The company's Chief Commercial Officer, Andrea Bricconi, emphasizes the critical importance of addressing the escalating power requirements in industrial settings. Bricconi highlights the significance of high efficiency solutions, particularly in the face of the surging demand for power driven by technologies like artificial intelligence.

One notable example of Cambridge GaN Devices' prowess is the GGD's 350 W PFC/LLC reference design, boasting an impressive power density of 23 W/in3. This design showcases an average efficiency of 93% and remarkably low no-load power consumption of 150 mW. By leveraging CGD's cutting-edge 650 V, 55 mΩ, H2 series ICeGaN technology, the CrM Totem Pole PFC + Half-Bridge LLC PSU delivers a robust 20 V / 17.5 A output.

Furthermore, a strategic partnership with Neways Electronics has resulted in the development of a high-performance 3 kW photo-voltaic inverter. This innovative solution effectively elevates the DC solar voltage to a stable DC link voltage, achieving a remarkable maximum efficiency of 99.22% through zero-current switching. The seamless integration of CGD's GaN HEMT structure with a standard silicon controller from Analog Devices Inc. underscores the user-friendly nature of the technology.

AGD Productions has also embraced ICeGaN technology in its AGD DUET amplifier, a compact yet powerful device rated at 300W 4Ω. This marks a significant milestone for AGD Productions, as it represents the company's first utilization of a 100% GaN power transistor design for both the power stage and the amplifier, showcasing the versatility and performance of CGD's solutions.

Lastly, the GaNext project, a collaborative effort involving 13 partners across three nations, has successfully introduced compact 1 kW intelligent power modules. These modules feature integrated drive, voltage control, and protection circuits powered by CGD's ICeGaN technology. The project exemplifies the transformative impact of Cambridge GaN Devices in driving innovation and efficiency across diverse industrial applications.
