Transphorm Delivers Highest Performance 600V GaN-on-Si Products

The firm says its GaN-on-silicon transistors, diodes and modules are ultra-efficient, compact, easy-to-embed and enable higher frequency compact systems. Transphorm says the devices cut energy lost by 50 percent

Transphorm has revealed its latest breakthrough in its cost-effective new products which reduce the large and growing problem of electrical energy waste in power conversion.

The company says it is the first company to provide a qualified 600V GaN solution to inefficient power conversion.

In 2011, the company announced its first GaN-on-silicon products: power transistors, diodes and modules, based on its patented, high-performance EZ GaN technology.

"The opportunity for widespread energy efficiency gains is staggering and our GaN solutions offer unprecedented energy gains," says Umesh Mishra, CEO of Transphorm. "In the motor segment alone, Transphorm's innovations create the potential to save 2.5 percent of U.S. electricity generation through enhanced electro-mechanical efficiency of the full drive and motor system--equivalent to the energy saving potential of replacing incandescent lighting with white LEDs."

Transphorm's efficient, compact, and easy-to-embed solutions cut energy waste by 50 percent today and simplify the design and manufacturing of a wide variety of electrical systems and devices, including motor drives, power supplies and inverters for solar panels and electric vehicles.

To demonstrate the performance advantage of its patented GaN based technology, Transphorm will showcase at the PCIM exhibition its EZ GaN based, DC-to-DC Boost Converter running at more than 99 percent efficiency and our Tru-Sine motor drive delivering 2-8 percent higher efficiency at 100 KHz vs. state of the art IGBT based motor drives at 15KHz.

"Our team continues to expand its lead in high voltage GaN, with a broad portfolio of transistors, diodes and modules- now possible on low cost silicon substrate platform," says Primit Parikh, President of Transphorm. "For customers looking for a low-risk roadmap to the next generation of power conversion technology, Transphorm's EZ-GaN Application Boards provide for a simpler design-in and faster time to market."

Electric power waste that occurs during power conversion is equivalent to the daily output of 318 coal plants, and it costs the U.S. economy $40 billion per year. Transphorm's GaN products come in industry-standard packages and are designed for optimum high-frequency switching. The company's proprietary EZ GaN platform can reduce power system size, increase energy density and deliver high efficiencies across the grid, from HVACs to hybrids, and from servers to solar panels.

The following Transphorm products are now available for sale as evaluation samples to approved customers:

TPS30xxPK series-- 600 V, 2-4-6 A, GaN diode in the industry standard TO-220 package

TPH3006PS- 600V, 180 mohm GaN transistor in the industry standard TO-220 package

TPT3044M- 600V, 3-ph GaN Module and related inverter application board TDMD2000E0I
