UK-based fabless, clean-tech semiconductor firm Cambridge GaN Gadgets (CGD) is demonstrating how its ICeGaN expertise brings the advantages of gallium nitride (GaN), together with effectivity, dimension and thermal administration, to purposes together with inverters, industrial energy provides and EVs.
The corporate’s Combo ICeGaN providing pairs its ICeGaN GaN built-in circuits (ICs) with IGBTs for electrical car inverters at 100 kW+, which it says enhance effectivity over conventional silicon merchandise and price lower than silicon carbide merchandise.
CGD has developed a 3-Stage ANPC EV inverter for 800 V traction with IFP Energies nouvelles (IFPEN), a French public analysis group. Enhanced motor efficiency, reliability and effectivity will increase inverter effectivity, lowers THD and reduces dV/dt on the motor. The inverter has a 650 V 25 m? full bridge 4-10 kW reference design.
The DHDFN package deal options double facet cooling to scale back thermal resistance, enabling excessive energy density, whereas dual-gate pinout simplifies PCB routing. Clear switching permits for full present (400 V, 120 A) in double-pulse check.
“By integrating the interface circuitry on the GaN chip together with the HEMT, ICeGaN may be very straightforward to make use of. Gadgets could be pushed utilizing a typical energy IC driver. Furthermore, it is vitally rugged and strong, and consists of additional safety circuitry, so reduces part rely,” mentioned Henryk Dabrowski, CGD’s Senior Vice President of World Gross sales. “Engineers are starting to understand that GaN could exchange SiC in sure excessive effectivity designs, attributable to its decrease manufacturing value.”
“CGD’s newest P2 sequence ICs characteristic RDS(on) ranges all the way down to 25 m?, supporting multi kW energy ranges with the best effectivity. We’ve got constructed a safe provide chain together with manufacturing offers with TSMC and ASE, and distribution by Digi-Key. With Combo ICeGaN, our expertise roadmap has been prolonged to handle EV purposes to over 100 kW,” mentioned Giorgia Longobardi, CGD’s founder and CEO.
