Cambridge GaN Devices (CGD) has raised $19m to start mass production of its smart GaN transistors and signed a key partnership deal.
The Cambridge University spinout developed gallium nitride transistors with added sensing to improve the efficiency of power systems.
The devices have been used in a 3kW solar panel inverter design by Neways in the Netherlands that is 99.2% efficient. The transformerless design, which uses eight CGD65A055S2 GaN transistors switching at 350kHz, was developed as part of the GaNext European project and has a power density of 1kW/L.
This is on display at the electronica show in Munich this week, where CGD is signing a partnership deal with Neways.
The Series B investment was led by Parkwalk Advisors and BGF, with participation from IQ Capital, CIC, Foresight Williams Technology and Martlet Capital.
“This latest round of investment is a great recognition of our success to date, with new and existing investors confirming the strength of our technology,” said said Dr Giorgia Longobardi, co-founder and CEO. “Since 2016, CGD has been on a mission to make greener electronics possible and to shape the future of power electronics by delivering the most efficient and easy-to-use transistors.
“We are thrilled to be in a position to move to mass production and global supply, delivering devices where our unique technology can have the biggest impact. GaN provides the optimum conversion solution, reducing power losses by more than 50% and increasing energy conversion efficiency to above 99%,” she said.
“To take just one application example, if all data centres were to adopt GaN, this would save 12.4TWh of electricity per year, or 9 million tons of CO2 – the equivalent of taking 1.9 million internal combustion engines vehicles off the road for a year. Our ICeGaN GaN transistors – which are now in the hands of customers at scale – are amongst the most efficient devices of their type on the market. Our devices are also the easiest for designers to use.”
As well as leading the $10m GaNext project, CGD is participating in a UK supply chain initiative for PCB-embedded power systems with GaN devices (P3EP) and recently launched a project to develop highly reliable GaN power transistors and ICs to cut data centre emissions (ICeData).
