Sunday 25th to Thursday 29th February, Booth 1543, Long Beach Convention Center, Long Beach, California
21st February 2024 – Innoscience Technology, the company founded to create a global energy ecosystem based on high-performance, low-cost, gallium-nitride-on-silicon (GaN-on-Si) power solutions, will continue to demonstrate industry-leadership at the upcoming IEEE Applied Power Electronics Conference and Exposition (APEC) 2024.
At the industrial session, Innoscience will address the exponential demand in power by datacenters due to the processing power necessitated by Artificial Intelligence (AI) applications. The paper will show that with Innoscience’s 650V InnoGaN, it is possible to make a 2kW AC/DC conversion PSU with a high power density and a peak efficiency above 96%, thereby meeting the recent stringent 80 Plus titanium efficiency rating. Thanks to the absence of a body diode on GaN devices, a simple Totem pole PFC architecture can be implemented while still reaching high levels of efficiency. At the booth Innoscience will also showcase a 4.2kW AC/DC conversion PSU meeting 80 Plus titanium efficiency rating within a power density of 130W/in3.
Moreover, to address the 48V to 12V DC-DC power conversion inside the data center, Innoscience will present an all GaN HEMTs based 1kW 48V-12V unregulated LLC solution that features GaN power devices both at the primary side (100V devices) as well as at the secondary side (40V devices). In order to maximize the power density and simplify the circuit, the solution uses Innoscience’s recent integrated SolidGaN solution (ISG3201), which integrates an half-bridge (made by two 100V/3.2mOhm InnoGaN devices) with its driver, protection etc.. in one package. The final all GaN 1kW 48V-12 converter has a size of only 50mmx30mmx9mm, which is 70% smaller than a Silicon counterpart rated only 600W. The converter achieves a peak efficiency of 98.5%.
Dr. Denis Marcon, General Manager Innoscience Europe, comments: “Reliability is also an important consideration for data centers, because they operate 24/7 and they must guarantee continuity of service. Therefore, in this paper we will also present strong reliability data of Innoscience’s HV and LV GaN power devices, including end-of-life testing for life-time calculation which shows reliability data at the parts-per-billion level.”
Yi Sun, General Manager Innoscience America comments: “Innoscience today has one of the widest portfolio of GaN power device solutions covering 30V to 700V applications, a family of GaN discrete available in standard packages (e.g. QFN, FCQFN, TO252 etc..) as well as integrated GaN IC solutions that include in one chip the GaN FET, the driver, protections etc.”
Visitors to the Innoscience booth at APEC will also see new products, such as the NV100FQ030A, a 100V bidirectional IC that can be employed to deliver high efficiency in applications including battery management systems, high-side load switching in bidirectional converters, and various switching circuits in power systems.
Yi Sun, adds: “Innoscience is leading the GaN industry with many new products that are industry firsts. That is why our devices are finding applications in all markets, from consumer chargers through industrial and communications and into the automotive sector. Join us at booth 1543 to find out more.”
