宜普電源轉換公司（EPC）宣佈推出100 V的EPC2052氮化鎵場效應電晶體，其占板面積只是2.25平方毫米、最大導通阻抗(R_DS(on))為13.5 mΩ及脈衝輸出電流高達74 A 以支援高效功率轉換。

針對DC/DC、雷射雷達（LiDAR）、無線電源及其他很多應用的客戶群正在不斷地擴大，宜普電源轉換公司（EPC）繼續其創新之路，在2019年3月及4月裡，於全球著名展覽會與設計工程師會面並答疑解難，旨在幫助工程師發揮氮化鎵技術的優勢，攜手打造共創共贏的局面。

宜普電源轉換公司(EPC)的專家於全球展覽會與設計工程師會面，希望加深與氮化鎵技術相關的知識交流，使得工程師可以利用基於氮化鎵元件的解決方案，創新新一代的設計。

EPC2112 and EPC2115 GaN-based monolithic integrated solutions offer power systems designers the ability to increase efficiency in an extremely small size.

EL SEGUNDO, Calif. — March 2018 — Efficient Power Conversion Corporation (EPC) announces the EPC2112 and EPC2115 enhancement-mode monolithic GaN power transistor with integrated driver products. The EPC2112 is a 200 V, 40-mΩ eGaN^® FET plus integrated gate driver. In comparison, the EPC2115 is an integrated circuit with dual 150 V, 70-mΩ eGaN FETs plus gate drivers. Both products are capable of operating up to 7 MHz and are available in low inductance, extremely small, 2.9 mm x 1.1 mm BGA surface-mount passivated die.

如果要無線充電得以普及， 無線充電系統必需從小型充電墊發展成為大面積無線電源。這就需要磁共振系統的線圈、系統架構及功率放大器各方面的基本改變。基於氮化鎵元件的放大器已經被證明為可以在廣闊的負載範圍內發送60 W功率至發射線圈並實現超過90% 的效率。

MIGVAN now represents EPC’s Israel sales, marketing, and technical support to assist customers in adopting eGaN^® FETs and ICs for leading-edge power conversion systems using gallium nitride

EL SEGUNDO, Calif.— October 2017 — To support its accelerating growth throughout Israel, Efficient Power Conversion Corporation (EPC) is proud to announce the appointment of MIGVAN as its sales, marketing, and technical support representative.  MIGVAN Technologies & Engineering Ltd, founded in 1988, is devoted to promoting and selling advanced technology electronic components and subsystems to the Israeli electronics industry.

Taking advantage of the high performance of eGaN^® FETs, Rompower Energy Systems has announced a reference design for a tiny, 65 W, 94% efficient AC/DC power adaptor for laptops and other mobile devices.

TUCSON, Az. – June 2017 – Rompower Energy Systems, an internationally recognized research and development company in the field of power conversion, announces the availability of technology for an extremely small, highly efficient AC/DC power adapter. In the quest for higher power density, the efficiency of the adapter is critical in order to decrease the heat dissipation. The reference design is measuring just 3.19 cubic inches in size, this adapter provides 65 W of power at greater than 94% efficiency over the entire input voltage range (90 V_ac – 264 V_ac).  The adapter has a power density of 20 W/in³. This high efficiency means that the device runs cooler than standard AC/DC adapters.
