This is a really critical demonstration of the need to create effective full manufacturing chains for the creation of game changing power solutions that take full advantage of the higher switching speeds possible with Compound Semiconductors. Packaging, circuit design and system designs need to be disrupted to accelerate the journey to net zero carbon.

We're thrilled to announce that our founder, Olivier de Laet, will be speaking this week at the prestigious CTI SYMPOSIUM - Automotive • Powertrain • Systems USA 2024. This event gathers industry leaders and experts from the automotive industry and Olivier will showcase how Calyos is pioneering the future of thermal management with our innovative two-phase cooling systems. Specifically, he will discuss the significant advancements we've made with Loop Heat Pipes (LHPs) and Micro Channel Heat Pipes (MCHP), technologies designed to enhance the cooling efficiency of power electronics, batteries, and embedded processors, all critical to the EV powertrain. It will include case studies demonstrating the successful application of our technologies. It will highlight systems capable of cooling kW's of heat with thermal resistances as low as 0.011K/W. Stay tuned for Olivier’s insights on how Calyos is collaborating with Tier 1 suppliers to bring these ground-breaking solutions to the automotive market. Our commitment to passive, efficient cooling is helping shape a cooler, more sustainable future for electric vehicles. Join us to discover how two-phase cooling is not just a technology shift, but a game changer for the industry! #CTI_Sym #CTISymposium #AutomotiveInnovation #ThermalManagement #EVcooling #Calyos

“GaN is a future-proofed and limitless technology. The advantages of our normally-off GaN are all backed by fundamental physics, [allowing] designers to develop applications that are smaller, lighter and more cost effective with lower switching losses, improved thermal performance and the ability to operate at higher frequencies.” - Philip Zuk on the inherent advantages of GaN for electric vehicle performance and innovation.    For more insights, register to access the full panel on-demand from the recent #AutomotiveTechForum, moderated by Power Electronics News’ Maurizio Di Paolo Emilio: https://lnkd.in/gdRAUfav    #TGAN #GaN #GalliumNitride #Semiconductor #EV #ElectricVehicle #RenewableEnergy #Technology
