Efficient Energy Technology GmbH(EET)位於奧地利，是設計和生產創新、用於陽臺的小型發電廠的先驅。EET公司選用了宜普電源轉換公司(EPC)的增强型氮化鎵(eGaN^®)功率電晶體（EPC2204）, 用於其新型SolMate^®綠色太陽能陽臺產品。EPC2204在低R_DS(on)和低C_OSS之間實現了最佳折衷，這對於要求嚴格的硬開關應用至關重要，同時在緊凑的封裝中實現100 V的汲-源擊穿電壓。這種緊凑型設計顯著縮小了PCB的尺寸，保持較小的電流廻路和最大限度地減少EMI。

EET公司結合了EPC的氮化鎵元件和其SolMate MPPT充電轉換器，以實現多種優勢：效率損失半和整體效率從96%提高到98%。轉換器的體積縮減了70%、BOM和製造成本降低了 20%，而且同時降低了對散熱的要求。此外，由於開關頻率提高了10倍，因此無需使用易於引發問題的電解電容器，從而延長了轉換器的使用壽命。

與採用傳統矽元件的轉換器相比，採用氮化鎵基高電子遷移率電晶體 (HEMT) 具有許多材料和性能優勢，已廣泛用於消費和工業用功率轉換領域。氮化鎵元件在更高的開關頻率下提高了功率轉換效率，進而實現更低的系統成本和更高的功率密度。隨著功率密度的增加，散熱分析和熱建模變得至關重要。我們將在本文分享EPC的熱量計算器。 EPC公司製造增强型 GaN HEMT 和集成電路，例如支持多種轉換器的半橋元件。

The space industry is undergoing a transformative shift to “New Space,” driven by the increasing demand for ubiquitous connectivity and the emergence of innovative business models. One of the key elements of this transformation is the adoption of gallium nitride (GaN) technology in space applications. GaN holds immense potential due to its impressive radiation hardness, high system efficiency and lightweight characteristics.

In a discussion with EE Times Europe, Taha Ayari and Aymen Ghorbel, technology and market analysts at Yole Intelligence, part of Yole Group, explained how New Space—the low Earth orbit (LEO) mission segment, with a typical satellite lifespan of three to five years and lower reliability requirements—has become a focal point for GaN adoption. As a result, power GaN devices are being adopted for various satellite systems, including DC/DC converters, point-of-load systems, motor drives and ion thrusters.

As more processing power and more complex loads are placed on-orbit or into deep space missions, it is sometime necessary to parallel two or more power switches. However, conventional power device packages, such as the FSMD-A/B/C/D and their I/O pad provisioning make it difficult to accomplish paralleling these devices in a performance-conscious manner. When paralleled, the gate and source-sense pads on these packages either serve to block the most efficient/shortest interconnect from package-to-package for the drain and source connections or for the gate and source-sense pads. So in parallel configurations, there is always a compromise between optimized drain-source load-circuit performance and gate-source-sense drive-loop performance. This article introduces the FSMD-G discrete HEMT package and explains how the reconfiguration of its I/O pads overcomes these limitations when paralleling GaN HEMTs.
