Alex Lidow is the CEO of Efficient Power Conversion, probably the most prominent advocate for gallium nitride, delivering the first GaN transistor in 2009. After a decade of selling products, DESIGN&ELEKTRONIK editor Ralf Higgelke met him to discuss some of the latest advances in that area.

On this episode of the Insomnicat Podcast, Nicolette and Bryan chat with Alex Lidow, CEO and Co- Founder of Efficient Power Conversion (EPC) about GaN technology. While many believe GaN is more costly than its predecessor, silicon, Lidow tells us that’s just a myth. Listen in as we talk about the future of GaN, the truth about Silicon’s reliability and get some advice for emerging engineers from someone who’s been in the industry for quite a while.

GaN and SiC are becoming much more attractive as prices drop. Several vendors are rolling out the next wave of power semiconductors based on gallium nitride (GaN) and silicon carbide (SiC), setting the stage for a showdown against traditional silicon-based devices in the market.

Artificial Intelligence (AI), gaming, cloud computing, and autonomous cars are all using the latest generation graphics processors (GPUs) in lieu of CPUs. The reasoning is that GPUs offer higher computational density than traditional CPUs as measured in terms of acquisition cost, size, and power requirements [Jensen Huang Keynotes NVIDIA’s 2018 GPU Technology Conference].
The implications for power architecture seem clear; 48 V will be the dominant voltage on the board with the GPU, and the final voltage will need to be somewhere around 1 V or less. Power levels are already around 1.5 kW and could soon go to as high as 3 kW per GPU. What is less clear is what will be the architecture for getting from 48 V to 1 V at these power levels.
