Modern solar panels are demanding increasingly higher power density and longer operating lifetimes. Solar applications including power optimizers and panels with built-in microinverters are becoming the prevailing trend for an increasing number of solar customers, where low voltage GaN power devices (V_DS < 200 V) are extensively used.

宜普電源轉換公司(EPC)發佈第十五階段產品可靠性測試報告，進一步豐富了關於氮化鎵元件可靠性的知識庫和展示了 EPC eGaN 產品的穩健耐用性已在實際應用中得到驗證。

EPC 宣佈發佈其第十五階段產品可靠性測試報告，記錄了持續使用測試元件至失效的方法，並針對太陽能優化器、光達感測器和DC/DC 轉換器等實際應用，加入了具體的可靠性指標和預測數據。

宜普電源轉換公司(EPC)推出200 V、10 mΩ的EPC2307，完善了額定電壓為 100 V、150 V和200 V的6個GaN電晶體系列，提供更高的性能、更小的解決方案和易於設計的DC/DC轉換、AC/DC SMPS和充電器、太陽能優化器和微型逆變器，以及馬達控制器。

全球增强型氮化鎵FET和IC領導者EPC推出 200 V、10 mΩ的EPC2307，採用耐熱增强型QFN封裝，佔位面積僅為3 mm x 5 mm。

Efficient Power Conversion (EPC) introduces the 150 V, 3 mΩ EPC2305 and the 200 V, 5 mΩ EPC2304 GaN FETs offering higher performance and smaller solution size and cost for DC-DC conversion, AC/DC SMPS and chargers, solar optimizers and microinverters, and motor drives.

EL SEGUNDO, Calif.— December 2022 — EPC, the world’s leader in enhancement-mode gallium nitride FETs and ICs, introduces the 150 V, 3 mΩ EPC2305 and the 200 V, 5 mΩ EPC2304 GaN FETs in a thermally enhanced QFN package with exposed top and tiny 3 mm x 5 mm footprint.

Efficient Power Conversion (EPC) introduces the 80 V, 4 mOhm EPC2619 GaN FET in tiny 1.5 mm x 2.5 mm footprint, offering higher performance and smaller solution size than traditional MOSFETs for high power density applications, including DC-DC conversion, motor drives, and synchronous rectification for 12 V – 20 V.

EL SEGUNDO, Calif.— November 2022 — EPC, the world’s leader in enhancement-mode gallium nitride (GaN) power FETs and ICs, launches the 80 V, 4 mOhm EPC2619. This is the lead product for a new generation of eGaN devices that have double the power density compared to EPC’s prior-generation products.

GaN FETs help Solarnative achieve industry-leading power density for solar microinverters, enabling module frame integration to solve the challenges of solar power installation.

EL SEGUNDO, Calif.— November 2022 Solarnative uses GaN devices in its new microinverter to achieve industry-best power density.  The Power Stick is the smallest inverter in the world, with dimensions of 23.9 by 23,2 by 404 millimeters. With an AC output power of 350 W, the volume of 0.19 liters corresponds to a power density of 1.6 kW per liter. By comparison, the IQ 7A microinverter from a market leading supplier delivers 349 watts with a volume of 1.12 liters, corresponding to 0.31 kW per liter – not even one-fifth of the Solarnative device. Despite the extreme size reduction, the European efficiencies are quite comparable, at 96.0 percent for the Power Stick and 96.5 percent for the IQ 7A.

宜普電源轉換公司 (EPC) 推出150 V、6 mΩ EPC2308 GaN FET，讓高功率密度應用實現更高的性能和更小的解決方案，包括 DC/DC轉換、AC/DC SMPS和充電器、太陽能優化器和微型逆變器，以及馬達控制器。

EPC是增强型氮化鎵 (eGaN®)功率FET和IC領域的全球領導者，新推採用更耐熱的QFN封裝且可立即發貨的150 V EPC2308氮化鎵元件，用於電動工具和機器人的馬達控制器、用於工業應用的80 V/100 V高功率密度 DC/DC轉換器、用於充電器、適配器和電源供電的28V~54V同步整流器、智能手機USB快速充電器，以及太陽能優化器和微型逆變器。
