GaN Systems co-founder joins QPT


Geoff Haynes, veteran of the GaN industry, joins UK start-up

Geoff Haynes, co-founder of GaN Systems and one of the pioneers of GaN technology. is joining UK start-up QPT as an advisor.

QPT’s qGaN module solution enables GaN transistors to be run at up to 20 MHz with nanosecond switching to deliver better operational precision. The technology in a Variable Frequency Drive (VFD), for example, enables motors to be driven at up to 99.7 percent efficiency at peak load with hardly any decrease in efficiency at lower loads. This overcomes a challenge for conventional designs today, where efficiency can drop off rapidly at lower loads.

Haynes said: “I have been following the progress of QPT’s technology with considerable interest. It solves the thermal and RF problems that GaN is now facing that currently form an insurmountable major barrier for the widespread use of GaN in high power, high voltage, hard switching applications."

He added: "I visited the company’s laboratory and was so impressed with its solutions that I am joining the company as an advisor to help them rapidly deploy this technology to the market. With it, GaN can now operate at the high frequencies needed to deliver significant power savings and open up applications worth billions as it provides a far superior performance and efficiency than SiC.”

Rob Gwynne, founder and CEO of QPT, added, “We are delighted that Geoff Haynes is coming onboard. He is a world authority on GaN and knows the challenges that it currently faces that limit its use. He immediately understood how our solutions and patents unlock the next phase in the evolution of GaN to become the enabling technology of choice for power electronics. Having him join and effectively putting his name behind QPT’s qGaN solutions is an incredible endorsement not only for customers but also for our upcoming Series A funding round.”
