The Trilogy of Wireless Power Transfer consists of three parts: Basics Principles of Wireless Power Transmission, Wireless Power Transfer Systems and Applications. The first part of the book explains the basic physical principles and the different methods of contactless power transmission. Furthermore, the leading standards are presented in this part. The second part describes wireless power transfer systems, the different topologies of wireless power transmission, the right selection of transmitter and receiver coils required to increase efficiency, and the selection of transistors, for instance. The third part is dedicated to practical applications. This includes applications within the scope of the Qi standard, as well as examples of proprietary solutions. An overview of EMI-relevant topics for closely and loosely coupled systems, as well as an example of a multimode wireless power transmission system round out the practical part. The authors of the "Trilogy of Wireless Power Transfer" are Cem Som, Division Manager Wireless Power Transfer at Würth Elektronik eiSos; and Dr. Michael de Rooij, Vice President Applications Engineering at Efficient Power Conversion Corporation, Inc. The book costs 19 euros and can be ordered from Würth Elektronik eiSos or through bookstores.

EPC introduces 100 V, 3.8 milliohm EPC2053 eGaN^® FET, joining the EPC2045, EPC2052, and EPC2051 to offer a comprehensive 100 V family of GaN transistors that are more efficient, smaller, and lower cost for high performance 48 V DC-DC conversion.

EL SEGUNDO, Calif. — April 2019 — Efficient Power Conversion Corporation, the world’s leader in enhancement-mode gallium nitride on silicon (eGaN) power FETs and ICs advances the performance capability while lowering the cost of off-the-shelf gallium nitride transistors with the introduction of the EPC2053 (3.8 mΩ, 100 V) eGaN FET.

專為功率系統設計師而設的EPC2052功率電晶體是一種100 V、13.5 mΩ並採用超小型晶片級封裝的電晶體，可實現74 A脈衝輸出電流。面向48 V-12 V DC/DC功率轉換器，這些新一代氮化鎵場效應電晶體工作在500 kHz頻率下，可實現超過97%的效率。如果工作在1 MHz時，則實現超過96%的效率。

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。

When the issue invariably turns to the packaging of the power semiconductor – transistor, diode, or integrated circuit – the requests for improvement fall into six categories:

1. Can you make the package smaller?
2. Can you reduce the package inductance?
3. Can you make the product with lower conduction losses?
4. Can you make the package more thermally efficient?
5. Can you sell the product at a lower price?
6. Can you make the package more reliable?

New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation Artificial Intelligence (AI) platforms. In all the topologies with 48 V_IN, the highest efficiency comes with using GaN devices. This is due to their lower capacitance and smaller size. With recent pricing declines in GaN power transistors, the cost comparison with silicon-based converters now strongly favors GaN in all the leading-edge solutions.

EPC will exhibit live demonstrations showing how GaN technology’s superior performance is transforming power delivery for entire industries including computing, communications, and automotive.

EL SEGUNDO, Calif. — March 2019 — The EPC team will be delivering eleven technical presentations on gallium nitride (GaN) technology and applications at APEC 2019 in Anaheim, California from March 17^th through the 21^st. In addition, the company will demonstrate its latest eGaN FETs and ICs in customers’ end products that are enabled by eGaN technology.

In the final installment of this series, how GaN has met the requirements to displace silicon is explored. As the adoption rate of GaN explodes, it is important to remember that, while GaN has made many advancements in just a few short years, it is still far from its theoretical performance limitations and thus there are profound improvements that can continue to be achieved. In time, the performance and cost advantages of GaN-on-silicon will result in a majority of applications currently using silicon-based devices converting to the smaller, faster, cheaper, and more reliable GaN technology.

繼第一至第九階段可靠性測試報告後，EPC公司的第十階段可靠性測試報告進一步豐富知識庫。此報告對超過30,000個元件進行了超過1,800萬小時的應力測試後，沒有元件發生故障。在過去的兩年間，我們所付運的數百萬個元件沒有發生現場失效的情況。

宜普電源轉換公司（EPC）發佈第十階段可靠性測試報告，成功通過車規級AEC-Q101應力測試認證。AEC-Q101認證要求功率場效應電晶體符合最高的可靠性標準，不僅僅要求元件符合數據表內所載的條件而沒有發生故障，也同時要求在應力測試中，具有低漂移。請注意，EPC所採用的晶圓級晶片尺寸封裝（WLCSP）也符合所有針對傳統封裝的測試標準，展示出該封裝具備卓越性能之同時沒有影響到元件的穩固性或可靠性。

In this conference GaN market and technology status will be addressed and its future evolution will be debated by mixing visions from designers, manufacturers, and end users.

EL SEGUNDO, Calif. — January 2019 — Efficient Power Conversion (EPC) is joining forces with Yole Développement (Yole) and SEMI to sponsor the first ever ‘GaN Con,’ an industry networking event covering the entire power GaN industry from manufacturers to end users. The theme of GaN Con is “Power GaN: From promises to possible market explosion” and is focused on the emerging GaN market and the state-of-the-art for its underlying technology.

氮化鎵元件對提升主流應用的效率的貢獻很大，例如在傳統矽基12 V - 1 V負載點 DC/DC轉換器。基於eGaN積體電路的12 V轉到1 V、12 A負載轉換器在5 MHz的頻率下，可以實現78%峰值效率及1000 W/in3 功率密度，而成本則低於每瓦0.2美元。
