10 MARKET NEWS Issue 2 2020 Power Electronics Europe www.power-mag.com The Flatpack2 60V SHE rectifier is Eltek’s third model in volume production featuring GaN power transistors, allowing for super high conversion efficiency of 98 %, significantly reducing energy loss and environmental footprint. With an output voltage of 60 V and power of 3 kW, the rectifier is particularly aimed at markets where 60 V applications are abundant, first and foremost Germany. Current power conversion equipment in these markets typically have conversion efficiency rates of around 90%. “Infineon’s CoolGaN power transistor is the key to the rectifier’s efficiency and reliability. Eltek benefits from the partnership with Infineon in the development of this potent technology, where Eltek’s role has been to test its behavior and suitability in real-life applications,” said CTO Lars Elstrøm. “True to the product’s inherent high efficiency, three committed engineers brought the project from the drawing board to delivery within weeks. In addition to the efficiency improvement, the GaN transistor technology brings improved reliability and is very well suited for efficient, fault-free manufacturing. The product is also backwards compatible with all 3 kW Flatpack2 versions, making it simple for customers to reap the benefits just by replacing modules.” www.eltek.com Eltek’s SHE is Going Greener with GaN Pre-Switch Appoints Foxy Power to Support AI-Based Switching To receive your own copy of subscribe today at: www.power-mag.com Pre-Switch has appointed Foxy Power GmbH from Berlin, Germany as its strategic partner for business development and sales. Founded in 2016, Pre-Switch has implemented soft-switching in DC/AC systems with varying input voltage, temperature and load conditions using AI to constantly- adjust the relative timing of elements within the switching system required to force a resonance to offset the current and voltage wave forms – thereby minimizing switching losses. “Foxy Power has efficiently approached top global automotive OEMs and automotive suppliers with our technology resulting in strategic design wins. They have also mapped these wins into further successes in industrial applications such as motor drives, battery chargers and renewables,” said Bruce Renouard, CEO of Pre-Switch. “Pre-Switch’s unique capability is bringing soft- switching to DC/AC and AC/DC inverters which significantly increases switching frequencies while reducing transistor costs. Their technology has shown added range for battery applications such as electric vehicle traction inverters and reduced the size, weight and system costs for industrial applications,” added Christopher Rocneanu, CEO and founder of Foxy Power. www.pre-switch.com
