600 V gallium nitride device is over 99% efficient
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.
“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.
TriQuint foundry supports Sarda Tech
TRIQUINT SEMICONDUCTOR has announced that its Foundry Services division is supporting start-up Sarda Technologies to bring a new line of high- efficiency DC-DC converter switches to the global marketplace.
Sarda, a ‘clean-tech’ company based in Durham, North Carolina in the U.S., plans to offer cost-saving solutions for increasing efficiency and reducing component size in smartphones, mobile PCs and similar applications.
“Sarda Technologies is a good example of the innovative commercial and defence start-ups our Foundry Services division supports. Sarda is developing an impressive family of power semiconductors for high-volume applications,” remarked VP and General Manager for Defence Products and Foundry Services, James L. Klein. “We offer a support system that enables a company’s first-to-market strategies including best-in-class modelling, program management and applications engineering teams dedicated to customer success.”

The global market demand for highly- efficient DC-DC switches for power converters is significant. According to the Darnell Group’s December 2011 report, the market is projected to grow from nearly 20 billion units in 2011 to just under 32 billion units in 2016, a 9.7% compound annual growth rate; global revenue is expected to grow to $4.3 billion. Power switching process technology currently utilised in DC-DC converters is not highly efficient. The switch is seen as an increasingly critical consumer electronics design element since power consumption dramatically impacts end-user product experiences. The higher efficiency, reduced size and cost-effectiveness of compound semiconductor-based technologies can be a definitive marketplace advantage.
Jeff Shepard, Darnell Group President said, “Sustained growth built on delivering improved DC-DC converters depends on innovative solutions. Sarda is a good example of a high tech company striving to deliver products that aim to meet these emerging requirements.”
