Transphorm’s High Voltage GaN Helps Inergy Disrupt The Solar Power Generator Market

Redesigned Kodiak Poised to Outperform Competitive Portable Electric Generators in Ruggedness, Weight, and Power Output

Transphorm, the gallium nitride (GaN) semiconductor, designer and manufacturer in partnership with solar energy company Inergy and design partner Telcodium has announced that the upcoming Inergy Kodiak Extreme will use high-voltage GaN to enhance the capabilities of portable power generators.

The soon-to-be-released Kodiak Extreme utilises a photovoltaic (PV) inverter and battery charger both integrating Transphorm's JEDEC-qualified GaN platform. These power systems are poised to make generators more powerful, lighter, and quicker to charge. And, given that GaN semiconductors run cooler than similar Silicon (Si) devices, the Kodiak Extreme does not require an internal cooling fan—allowing Inergy to develop one of the first truly water-resistant and dustproof solar power generators for consumers.

GaN Benefits Realised
The Kodiak Extreme has a 110/120 Vac 2 kW output. The generator targets consumers and professionals [construction, emergency services, industrial, etc.] by providing reliable off-grid AC power. The solar generator's PV inverter and battery converter use Transphorm's TP65H050WS 50 mΩ TO-247 FET and TPH3206LDGB 150 mΩ PQFN device respectively.

“We've been interested in Gallium Nitride power systems for some time, having first been introduced to it observing the Google Little Box Challenge,” said James Brainard, CTO of Inergy. “The technology's capabilities would allow us to create a highly ruggedized and efficient portable generator capable of bringing affordable solar energy to the masses. Superior durability, high clean power output, lightweight—these are all the attributes that our customers want. Working with Transphorm and Telcodium to develop the GaN platform for our system enables us to achieve that vision.”

The Kodiak Extreme will be unveiled at Power-Gen International 2018, giving conference attendees a preview of one of the industry's first GaN-based portable solar generator. Commercial release is slated for Q1 2019.
