Transphorm introduces first qualified 600V Gallium Nitride product and demonstrates 99+% efficient DC-DC boost converter

GaN (gallium nitride) power electronics provider Transphorm Inc. (earlier post) announced the qualification of its first products, power diodes based on its EZ-GaN (Gallium Nitride) technology, at the Applied Power Electronics Conference (APEC):

  • 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 solutions cut energy waste by 20% 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, according to the company. To demonstrate the performance advantage of the GaN-based technology, Transphorm will showcase at the APEC exhibition a EZ-GaN-based, DC-to-DC Boost Converter running at more than 99% efficiency.

Transphorm is the first to provide a qualified 600 volt 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 for a range of power electronics applications.

Not a penny of government money should be spent for new more efficient technology until the governments eliminate high oil prices caused only by speculation and greed not by the cost to get it out of the ground.

Because of a failed policy instituted over 30 years ago the US is wasting 99 percent of its uranium fuel. Why worry about tungsten light bulbs when you have already thrown away fuel that could power such bulbs for hundreds of years. Getting rid of personal automobiles with more than 40 kW would save a lot more energy.

However; these diodes could accelerate the adopting of the more efficient direct current for factories, homes and all buried electric transmission lines.

Just glad to see this higher efficiency power technology on the market.

But it is disgusting to see politicians fail to solve an oil energy problem that's been in our faces since the 1973 OPEC oil embargo.

All this s@#% "we'll debate and pass a law for ten/twenty years from now", which everyone knows they'll take new lobbying/bribes for debating and rewriting each following year/term, is crap.

The space race was basically a pissing match, but at least it got technical breakthroughs and gave direction for fifteen years.

Solar energy is free, and is getting to be as cheap as fossil fuel energy in the near future. Why worry about nuclear energy. This conversion device will be great to facilitate mass adoption of DC electricity from PV panels, from storage battery, or from H2 fuel cells.

This looks like it will feature in EV chargers and high-power inverter drives. Switching high DC voltages at high efficiency is the name of the game there. Even so, it will take quite a few of these devices to handle even a single channel of a 3-phase motor drive for an EV.

That was what I was thinking, but one step at a time. I don't imagine these devices are cheap, but for an application that requires them, they could be essential.
