Eltek Launches the Flatpack2 SHE, a Super High Efficiency Power Conversion Module with the New Game Changing CoolGaN™ Technology from Infineon at Its Core

10 Oct

The quest for improved power conversion efficiency and reduction of energy losses is always on. In close co-operation with Infineon Technologies AG, Eltek engineers have again cracked the code, reducing power conversion losses by 50% while further improving reliability and total cost of ownership.

Eltek is today announcing the launch of the Flatpack2 SHE, a new Super High Efficiency power conversion module. After the revolution Eltek started with the HE technology, there has been a decade of smaller, incremental improvements. To make a significant change in conversion efficiency, reliability and total cost of ownership, Eltek saw the need to bring in new technology. The company selected the “CoolGaN™” from Infineon; the close co-operation with Infineon throughout the development, verification and industrialization process is unique in the company’s history.

“Reaching the 98% efficiency target, while improving an already industry-leading field performance in a competitive way, gives us a system that will be appreciated by our customers – especially telecom and data center customers,” said Morten Schoyen, Chief Marketing Officer at Eltek. “With our customers in focus we have also built in backward compatibility to all 3kW Flatpack2 versions. In other words, efficiency upgrades have never been simpler as the older modules can just be replaced,” added Mr. Schoyen.

The Flatpack2 SHE will have a substantial impact on carbon footprint, consumed energy and ultimately energy-related operational expenses of Eltek customers. The energy savings are illustrated by the following examples where early versions of Flatpack 2 (92 percent efficiency) were replaced with Flatpack2 SHE:

  • Single mobile base station in Italy, 6kW load – annual saving: € 576
  • Central office site in UK, 250 kW load – annual saving: £ 18,350

“We always seek to stay ahead of the game on technology, and the ability to incorporate game-changing technology like the CoolGaN™ from Infineon is key to achieving this goal. Besides the efficiency improvement, this technology brings improved reliability, manufacturability and other advantages that will enable us to continue to lead this industry,” said Erik Myhre, Senior R&D Manager at Eltek.

“We are delighted that Eltek is now manufacturing AC/DC power converters featuring our CoolGaN™ technology,” said Dr. Steffen Metzger, Senior Director High Voltage Conversion for Infineon Technologies. “They prove the value of GaN devices for achieving the highest electrical conversion efficiency at attractive system cost. We are also encouraged by the results of Eltek’s tests that show that the GaN-based systems are rugged and reliable, as expected. This validates Infineon’s application specific qualification methodology which allows us to predict useful life of our CoolGaN™ devices in a given application.”
