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.

Powering Graphics Processors from a 48 V Bus

Introduction

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.

SAN FRANCISCO — Alex Lidow has sold semiconductors in China for decades, starting at a company, called International Rectifier, that his father and grandfather founded in the Los Angeles area in 1947.

Now Mr. Lidow runs Efficient Power Conversion, which makes chips that manage electrical power in cars and other products. Efficient Power has a strong foothold in China, but has lately run into resistance from customers there that he traces to moves in Washington.
