Cambridge GaN Devices (CGD) announced that Inventchip, a leading provider of SiC power devices and IC solutions headquartered in Shanghai, has successfully demo’d a 2.5 kW GaN-based CCM totem-pole PFC reference design using CGD’s ICeGaN® gallium nitride ICs. A key feature is ease-of use. ICeGaN ICs integrate interface circuitry and protection on the same GaN die as the HEMT. Therefore, any standard driver IC can be used. The Inventchip IVCC1104 totem pole PFC controller IC is also simple to use with no programming required. It offers optimized AC zero-crossing control, low THD and high robustness against AC disturbance.
DI CHEN | DIRECTOR, TECHNICAL MARKETING AND BUSINESS DEVELOPMENT, CGD
“Inventchip had an existing 2.5kW TPPFC reference design based on its controller and gate drivers using SiC MOSFETs in TO-247 packages. To evaluate the performance of GaN instead, Inventchip designed a TO-247 adapter board using our P2 25mΩ ICeGaN ICs and the ICeGaN design works perfectly without any modification of their circuits. It has demonstrated that the ICeGaN can significantly shorten the learning curve and allow engineers to bring new product faster to market.”DR. ZHONG YE |CTO , INVENTCHIP
“By using a TO247-4 adapter board to solder on a DFN-packaged ICeGaN device for a quick test on our EVM, despite the relatively long gate drive path and the extended drive power supply trace, the board was powered up successfully at the first shot with clean switching waveform. No abnormalities or shoot-through was observed from no-load to full-load conditions. The GaN’s performance is very impressive. The CGD GaN device has proven to be very noise-immune, user-friendly and highly efficient.”Having proved its efficiency and power density in low power charger designs, GaN is now being adopted by makers of server and data centre PSUs, inverters, industrial brick DC/DC converters and LED drivers. Soon, EV inverter drives of over 100 kW are expected to transition to GaN too. ICeGaN technology is especially suitable at higher power levels because of its proven reliability and robustness.

Cambridge GaN Devices revealed more details about a solution that will enable the company to address EV powertrain applications over 100kW – a market worth over $10B – with its ICeGaN® gallium nitride (GaN) technology. Combo ICeGaN® combines smart ICeGaN HEMT ICs and IGBTs (Insulated-Gate Bipolar Transistors) in the same module or IPM, maximizing efficiency and offering a cost-effective alternative to expensive silicon carbide (SiC) solutions.
Dr GIORGIA LONGOBARDI | FOUNDER AND CEO, CGD
“Today, inverters for EV powertrains either use IGBTs which are low cost but inefficient at light load conditions, or SiC devices which are very efficient but also expensive. Our new Combo ICeGaN solution will revolutionise the EV industry by intelligently combining the benefits of GaN and silicon technologies, keeping cost low and maintaining the highest levels of efficiency which, of course, means faster charging and longer range. We are already working with Tier One automotive EV manufacturers and their supply chain partners to bring this technology advancement to the market.”The proprietary Combo ICeGaN approach uses the fact that ICeGaN and IGBT devices can be operated in a parallel architecture having similar drive voltage ranges (e.g. 0-20V) and excellent gate robustness. In operation, the ICeGaN switch is very efficient, with low conduction and low switching losses at relatively low currents (light load), while the IGBT is dominant at relatively high currents (towards full load or during surge conditions).
Combo ICeGaN also benefits from the high saturation currents and the avalanche clamping capability of IGBTs and the very efficient switching of ICeGaN. At higher temperatures, the bipolar component of the IGBT will start to conduct at lower on-state voltages, supplementing the loss of current in the ICeGaN. Conversely, at lower temperatures, ICeGaN will take more current. Sensing and protection functions are intelligently managed to optimally drive the Combo ICeGaN and enhance the Safe Operating Area (SOA) of both ICeGaN and IGBT devices.
ICeGaN technology allows EV engineers to enjoy GaN’s benefits in DC-to-DC converters, on-board chargers and potentially traction inverters. Combo ICeGaN further extends the benefits of CGD’s GaN technology into the rich 100kW+ traction inverter market. ICeGaN ICs have been proven to be very robust and IGBTs have a long and proven track record in traction and EV applications. Similar, proprietary parallel combinations of ICeGaN devices with SiC MOSFETs have also been proven by CGD, but Combo ICeGaN – which is now detailed in a published IEDM paper – is a far more economical solution. CGD expects to have working demos of Combo ICeGaN at the end of this year.
Prof. FLORIN UDREA | FOUNDER AND CTO, CGD
“Having worked for three decades in the field of power devices, this is the first time I have encountered such a beautifully complementary technology pairing. ICeGaN is extremely fast and a star performer at light load conditions while the IGBT brings great benefits during full load, surge conditions and at high temperatures. ICeGaN provides on-chip intelligence while the IGBT provides avalanche capability. They both embrace silicon substrates which come with cost, infrastructure and manufacturability advantages.”CGD will be exhibiting at APEC (Applied Power Electronics Conference and Exposition).

Cambridge GaN Devices (CGD) and IFP Energies nouvelles (IFPEN), a major French public research and training organization in the fields of energy, transport and the environment, have developed a demo which confirms the suitability of CGD’s ICeGaN®650 V GaN ICs in a multi-level, 800 VDC inverter.
The demo delivers super-high power density – 30 kW/l – which is greater than can be achieved by more expensive, state-of-the-art silicon-carbide (SiC)-based devices. The inverter realization also demonstrates the ease of paralleling that ICeGaN technology enables; each inverter node has three 25mΩ / 650V ICeGaN ICs – 36 devices in total – in parallel.
ANDREA BRICCONI | CHIEF MARKETING OFFICER, CGD
“We are super excited at this first result of our partnership with IFPEN. 800 VDC supports the 800 V bus which is being increasingly adopted by the EV industry. By addressing automotive and other high voltage inverter applications with energy-efficient ICeGaN-based solutions we are delivering on CGD’s key commitment – sustainability.”This multi-level GaN Inverters can power electric motors to over 100 kW peak, 75 kW continuous power. The CGD/IFPEN demo features: a high voltage input of up to 800Vdc; 3-phase output; a peak current of 125 Arms (10s) (180 Apk); and a continuous current of 85 Arms continuous (120 Apk).
The ICeGaN multi-level design proposed by IFPEN reveals several compelling benefits:
- Increased Efficiency: the improvement in the efficiency of the traction inverter leads to an increase in battery range and a reduction in charging cycles. It also leads to a reduction in battery cost if the initial range (iso-range) is maintained
- Higher switching frequencies: GaN transistors can operate at much higher frequencies than silicon transistors. This reduces iron losses in the motor, particularly in the case of machines with low inductances
- Reduced Electromagnetic Interferences: 3-level topology minimizes EMI and enhances the reliability of the system
- Enhanced thermal management: insulated metallized substrate boards featuring an aluminium core facilitate superior thermal dissipation, ensuring optimal operating temperatures and extending the lifespan of the system and associated GaN devices
- Modular design: this facilitates scalability and adaptability for varying system requirements.
GAETANO DE PAOLA | PROGRAM MANAGER, IFPEN

Cambridge GaN Devices (CGD) will exhibit at Electronica which runs from November 12-15, 2024 at the Messe München, Munich, Germany. This will be the second time that the company has exhibited at the world’s leading trade fair and conference for electronics, marking the company’s position as a leader in delivering gallium-nitride power ICs which are easy to use and very reliable.
ANDREA BRICCONI | CHIEF MARKETING OFFICER, CGD
“Since our first appearance at Electronica, CGD has made remarkable steps. We have introduced our P2 series ICeGaN® ICs that feature RDS(on) levels down to 25 mΩ, supporting multi kW power levels with the highest efficiency. We have announced a deal with TSMC, the leading IC fabrication house in the world which ensures quality and supply of our innovative power devices. Also, studies by leading academic research establishment, Virginia Tech University, have demonstrated that our ICeGaN GaN technology is more reliable and robust than other GaN platforms. GaN is now available for use at higher power levels, and at Electronica we are expecting to meet with designers who are eager to take advantage of the efficiency and power density benefits that GaN can bring to their latest designs.”During the show, CGD will make two presentations:
- November 12, 13:20 – 14:10, Booth A5.351: SiC & GaN Technologies – Exploring Advancements, Addressing Challenges CGD’s CTO and co-founder, Professor Florin Udrea will join a panel of GaN experts for a Panel Discussion moderated by Maurizio Di Paolo Emilio, Editor-in-Chief, Power Electronics News.
- November 12, 16:10-16:35, Power Electronics Forum: ICeGaN as a smart high voltage platform for high power industrial and automotive applications presented by Professor Florin Udrea.
The power devices field has undergone significant change due to the emergence of Wide Band Gap semiconductors, particularly Gallium Nitride (GaN) and Silicon Carbide (SiC). Traditionally, GaN has been used for lower power consumer applications (e.g., power supplies), while SiC dominated the medium to high power markets, such as industrial (e.g., motor drives) and automotive applications (e.g., traction inverters).
SiC’s superior scaling of on-state resistance at high voltages gives it an edge above 1.2 kV, but GaN is now competing with SiC at 650V for all power levels. ICeGaN®, featuring sensing and protection functions, surpasses discrete SiC in terms of robustness and ease of paralleling, offering notable advantages for 650V high-power applications. Additionally, with the rise of multi-level topologies for traction inverters, GaN may challenge SiC’s 1.2 kV market. Ultimately, both technologies have a bright future, with overlap expected in high-power (10-500 kW) applications.
At Electronica, CGD will show a number of demos that employ ICeGaN, including:
- 3 kW totem-pole PFC evaluation board;
- High and low power QORVO motor drive evaluation kits developed in collaboration with CGD and utilising ICeGaN
- Half-bridge and full-bridge evaluation boards, plus an ICeGaN in parallel evaluation board;
- Single leg of a 3-phase 800 V automotive inverter demo board, developed in partnership with French public R&I institute, IFP Energies nouvelles (IFPEN);
