EPC宜普电源转换公司（EPC）是基于氮化镓（GaN）功率管理技术的领导供应商，EPC宜普不仅仅致力于提高电力效率，更利用氮化镓技术推动了五年前不可能实现的并显著提升生活的全新应用。由于多种应用例如从无线电源传送、全自动汽车以至高速移动通信、低成本卫星及医疗护理应用都不断蜕变，因此氮化镓技术成为勇于革新、持续前进和渴望保持行业领先地位的公司的首选技术。

EPC宜普电源转换公司于2007年11月由三位资深工程师共同创建，他们合共拥有六十年与先进功率管理技术相关的经验。EPC宜普电源转换公司的首席执行官Alex Lidow是1970年代硅功率MOSFET的共同发明者。在国际整流器公司曾担任管理研发及制造职位外，期间更有长达十二年担任该公司的首席执行官。其后半导体技术的发展进程让宜普公司的所有创办人清楚知道硅技术已经达到它的性能极限及其发展步伐已经不可以像从前那样为业界推动创新、再创高峰。

创建EPC宜普电源转换公司是基于对氮化镓技术可以在电源转换领域替代硅技术的信念， 这是由于氮化镓技术具备无敌的速度、效率及低成本的优势。其实氮化镓技术是一种具备优越的晶体特性的使能技术，它可以实现的性能与硅技术相比较是1000 ：1 的比值。

EPC宜普公司于2009年6月推出第一款商用增强型氮化镓（eGaN®)晶体管。这些全新的器件在台湾晶圆代工厂制造，该厂制造标准硅IC，是一个成熟、高效及低成本的供应链，使得氮化镓晶体管格外的可靠及并不昂贵。目前EPC宜普公司提供超过100 种产品，面向全球130亿美元的市场。

60年以來氮化鎵元件是是第一种具备更高性能及更低成本的元件并可以替代硅元件。目前EPC宜普公司与全球多家领先行业的公司携手利用氮化镓使能技术推动它们的新一代技术的发展。使用氮化镓产品的公司可以避免因为使用旧有硅器件而落后、推动公司业务增长及提升终端用户价值。

EPC is the leading provider of gallium nitride (GaN)-based power management technology and is doing more than just improving efficiency of electrical power. It is also enabling new, life-changing applications that didn’t exist five years ago. From wireless power and autonomous vehicles to high-speed mobile communications, low cost satellites, and transformations in medical care, among many others, GaN is becoming the preferred technology for progressive companies that are eager to remain at the forefront of their industries.

EPC was founded in November 2007 by three engineers, with a combined 60 years of experience in advanced power management technology. EPC’s CEO Alex Lidow was the co-inventor of the silicon power MOSFET in the 1970s; and, in addition to holding positions in R&D and manufacturing, was the CEO of International Rectifier for 12 years. Over time it became clear to the founders of EPC that silicon had reached its performance limits, failing to propel innovation forward at the rate to which we had become accustomed.

EPC was founded with the foresight that GaN would be the inevitable successor to silicon in the advancement of power because of its incomparable speed, efficiency, and low cost. In fact, GaN has superior crystal properties that enable a performance advantage over silicon by as much as 1000:1.

In June 2009, EPC delivered the first commercial enhancement-mode GaN (eGaN®) transistors. These new devices were manufactured in a Taiwanese foundry designed to produce standard silicon integrated circuits creating a mature, efficient, and low cost supply chain, making its GaN transistors extraordinarily reliable and affordable. Today EPC offers more than 100 products that address a $13 Billion market.

For the first time in 60 years there is a higher performance and lower cost option to silicon…gallium nitride. Today, leading companies the world over work with EPC to enable their next generation technologies with the power of GaN. Companies that leverage GaN can avoid being left behind with aging silicon, drive sales growth, and deliver increasing end-customer value.
