工研院举办无线电能传输研讨会，邀请了来自AirFuel 无线充电联盟、宜普电源转换公司（EPC）、jjPLUS和IHS Markit的业界领袖进行专家演讲。

2018年10月30日 - 人们对5G、笔记本电脑、机器人、机械工具和医疗设备等新应用的中高功率无线充电（WPT）需求不断增加，无线电力的下一个杀手级应用将会是什么?

为了解答这个问题并旨在推动基于高效无线充电标准的产业发展，台湾工业技术研究院ITRI的区域与两岸工作小组、AirFuel无线充电联盟、宜普电源转换公司（EPC）和jjPLUS公司携手支持首届“无线电能传输（WPT）结合5G新应用研讨会”。活动于2018年10月30日（星期二）在台北的国立台湾大学博理館演讲厅举行。

从2010年开始，自硅基氮化镓（GaN）晶体管商用化后，低压氮化镓晶体管推动了很多全新应用的发展。氮化镓器件具备超快速开关，推动全新市场诸如激光雷达、包络跟踪及无线电源市场的出现。这些全新应用进一步实现更强大的供应链、低制造成本及器件前所未有的高可靠性。这些优势使得比较保守的设计工程师在DC/DC转换器、AC/DC转换器及车载等各种应用开始对氮化镓器件进行评估。在本文章系列，我们将讨论多种发挥氮化镓器件优势的应用，实现最终产品差异化的竞争优势。首先，我们会探讨是什么因素加快了氮化镓器件的普及。

LAS VEGAS — Once again the marathon that is CES is drawing to a close. Four days of trade show plus two days of media events. All sprawled across five miles of Las Vegas in some insane number of hotels and conference venues. As usual, I stuck it out so you don’t have to. Here are some of the images that struck me as interesting, weird, or just plain worth remembering:

Wireless power, the ability to deliver electricity to gadgets without plugging those gadgets into a cable, is a hotbed of innovation at the moment. The dominant standard, called “Qi,” is ever under attack from other efforts.

This week saw interesting developments from Energous (WATT), which aims to transfer power via radio frequency transceivers, with limited results so far, and some controversy about its business.

There are other contenders. On Wednesday in Las Vegas, during the Consumer Electronics Show, I met with Alex Lidow, who is founder of a privately held chip company EPC of El Segundo, California.
