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 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.

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.

Power Integrations announced that it has completed the acquisition of CT-Concept Technologie AG (known as CONCEPT), effective May 1.

Concept's highly integrated, energy-efficient products are used in a range of high-voltage power-conversion applications including industrial motor drives, renewable energy generation, electric trains and trams, high-voltage DC transmission, electric cars and medical equipment.

Revenues increased eight percent sequentially to $71.8 million; cash flow from operations was $21.6 million

The California Energy Commission (CEC) recently published a schedule outlining when efficiency enforcement rules will come online for various product groups. As enforcement rules go into effect, penalties and collection procedures will be levied against violators.

A verdict has been reached in Power Integration's 2008 patent-infringement lawsuit against Fairchild Semiconductor. After a three-week trial in the U.S. District Court for the District of Delaware, a jury found that Fairchild infringes two Power Integrations patents. The infringement findings cover approximately 75 Fairchild products.

At a stakeholder webinar held earlier this month, the U.S. Department of Energy began the process of making final changes to the latest draft of its ENERGY STAR set-top box spec. The new spec is scheduled to become effective in July of 2013.

To learn more about the new spec and the recent webinar, read Mr. Green's Blog.

Three new videos have been added to the Power Integrations website. They show the benefits of using Qspeed diodes in CCM boost PFC circuits, as output rectifiers, or as anti-parallel diodes bridge inverters.
