Transphorm will demonstrate the product built with its customer-partner Yaskawa Electric, Japan at the upcoming APEC 2013 industry conference. The announcement underscores the technical and commercial progress that Transphorm has made since being awarded ARPA-E funding in 2011 to reduce the amount of electric power waste globally.

Yaskawa’s product, a 4.5 kW PV power conditioner, is powered by Transphorm’s 600 V GaN half-bridge modules, which have enabled it to achieve several industry firsts:

    The first high power converter product in the world utilizing GaN technology
    The first efficient PV power conditioner to operate at 50KHz
    Simultaneous achievement of a 40% reduction in inverter size and 98% efficiency operation, a form and function benefit uniquely enabled by Transphorm’s EZ-GaN module technology

Transphorm’s patented, high-performance EZ-GaN module technology, combines low switching and conduction losses offering reduced energy loss of over 50% compared to conventional silicon based power conversion designs while simultaneously operating at higher frequency.

“The partnership between Yaskawa, the world leader in inverter solutions, and Transphorm, the world leader in GaN-based power conversion, has produced the world’s first high power GaN power converter,” said Umesh Mishra, CEO of Transphorm. “This is a disruptive first step which signals the broad adoption of GaN-based power conversion solutions.”

Transphorm’s efficient, compact, and easy-to-embed solutions simplify the design and manufacturing of a wide variety of electrical systems and devices, including power supplies and adapters, PV Inverters for solar panels, motor drives and power conversion for electric vehicles.  Transphorm’s proprietary EZ- GaN platform can reduce power system size, increase energy density and deliver high efficiencies across the grid.
