An ENERGY STAR third-party testing requirement that went into effect at the beginning of the year is now being met with some resistance by manufacturers. The issue begs the question: When does the expense of efficiency labeling become cost-prohibitive?

SemiSouth正在交付业界首款650 V碳化硅JFET功率晶体管。这些器件具有快速开关速度、大电流处理能力以及出色的SiC 热性能，因此非常适合电力电子应用。它们采用垂直沟道JFET结构，可达到业界领先的每单位面积低导通电阻，比同类竞争技术低五到十倍。

PI现在代表SemiSouth Laboratories推出其专用碳化硅晶体管和二极管产品。如需阅读更多有关SemiSouth此项及其他产品资讯的信息，请访问SemiSouth网站。

SemiSouth is delivering industry's first 650 V silicon carbide JFET power transistors. The fast switching speeds, large current handling capability combined with the superior thermal properties of SiC makes these devices ideal candidates for power electronic applications. They employ vertical trench JFET structures, which allow for industry-leading on-resistance per unit area, as much as five to ten times lower than competing technologies.

PI's new video introduction to SemiSouth Silicon Carbide diodes demonstrates the performance you may be missing.

在最近于意大利举行的欧盟委员会生态设计指令会议上，各利益相关方明确支持提高外部电源的(EPS)的效率限值。此外，其法规制定机构还表现出了要与美国能源部(DoE)新提议的EPS标准看齐的强烈愿望。

如想了解Mr. Green对这一新动向的看法，请访问绿色空间。

At a recent EC Code of Conduct meeting in Italy, stakeholders expressed an interest in tightening efficiency limits for external power supplies (EPSs). The group also showed a desire to harmonize with the U.S. DoE's new proposed EPS standards.
