Industry's first qualified 600 V gallium nitride device is over 99% efficient
Transphorm's 600 V DC-DC boost converter diodes which use its patented EZ-GaN technology are ultra-efficient, compact and easy-to-embed, and cut energy loss by 20 percent
At the Applied Power Electronics Conference (APEC), Transphorm revealed its newest step to solve the large and growing problem of electrical energy waste in power conversion.
The company announced the qualification of its first products, power diodes based on its patented, high-performance EZ-GaN technology:
TPS2010PK -- 600 V, 6 A, GaN diode in the industry standard TO-220 package
TPS2011PK -- 600 V, 4 A, GaN diode in the industry standard TO-220 package
TPS2012PK -- 600 V, 2 A, GaN diode in the industry standard TO-220 package
These products are now qualified and available for sale through the Transphorm web site to approved customers.
Transphorm's efficient, compact, and easy-to-embed solutions cut energy waste by 20 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 APEC exhibition our EZ-GaN based, DC-to-DC Boost Converter running at more than 99 percent efficiency.
"As predicted at APEC 2011, we are pleased to announce the availability of our first qualified products at APEC 2012 and showcase our technology to customers, partners and other stakeholders, as examples of our commitment to demonstrate that GaN devices for power are moving into mainstream adoption" said Umesh Mishra, CEO of Transphorm. "Our EZ-GaN solutions also impact broad applications such as motor drive systems where our products provide 2-8% electromechanical efficiency gains."
"Our team lays the key first stake in the ground demonstrating that 600V GaN is not just a long-term promise, but today a superior product - an accomplishment made possible by working closely with our customer-partners who deliver the end products for power conversion", said 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 provides a cost-effective, customizable and easy-to-use solution ready for commercial scale."
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 reckons it is the first company to provide a qualified 600 V GaN solution to inefficient power conversion.
The GaN products come in industry-standard packages and are designed for optimum high-frequency switching. Transphorm'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. Transphorm will be showcasing its products at booth # 226 at APEC.
