Cambridge GaN devices and IFPEN to develop automotive inverter

Author: EIS Release Date: Dec 29, 2022

Cambridge GaN Devices (CGD),  has signed an agreement with IFP Energies nouvelles (IFPEN), a French public research and training organisation in the fields of energy, transport and the environment, to develop an innovative automotive inverter using advanced GaN devices.

 

“Technological innovation is central to all IFPEN’s activities,” says Georgia Longobardi, founder and CEO of CGD (pictured) “therefore we are particularly excited that IFPEN has chosen CGD’s ICeGaN GaN HEMTs in this new automotive inverter design. IFPEN also shares CGD’s belief that close partnerships with key players are essential to the success of any project, so we are proud to be part of this program.”

 

“This partnership with CGD is a key element for our future activities in power electronics for e-mobility, specifically for next generation of inverters where a technological step is required to reduce size and increase power density levels while challenging the cost,” says Gaetan Monnier of IFPEN, “we count on the cooperation with this young and dynamic, extremely innovative company to address the ambitious challenges critical to the future of e-mobility industries.”

 

The partnership between IFPEN and CGD combines two complementary areas of expertise. IFPEN understands the automotive market and its performance targets. IFPEN possesses a strong position in inverter and software development, with in-depth knowledge of the algorithms and equipment required.

 

CGD’s GaN technology has resulted in a scalable 650 V GaN HEMT family. The company’s ICeGaN H1 series are single-chip eMode HEMT devices that can be driven like a MOSFET, without the need for special gate drivers, complex and lossy driving circuits, negative voltage supply requirements or additional clamping components.

 

ICeGaN  HEMTs require no cascode structure, no complex multi-chip configurations, and no thermally-complex integrated solutions. Instead, they are a single-chip solution with embedded proprietary logic which enables the coupling with standard gate drivers or controllers.

 

The devices are suitable for demanding application environments, as found in the automotive market.
