Achieving efficiencies greater than 98% in conventional Power Factor Correction (PFC) circuits is challenging. The major hurdle is fixed diode bridge losses. An option to overcome this is to use silicon MOSFETs in place of the diodes to achieve efficiencies of 99% or more. However, this BTPPFC approach suffers from poor reverse recovery performance, is […]
Podcast: Where engineers trying to learn power GaN get into trouble
Gallium nitride (GaN) is one of the technologies that could well displace silicon MOSFETs in the next generation of power transistors. As silicon approaches its performance limits, GaN devices conduct better and switch faster. But GaN devices don’t behave the way silicon power devices do. That’s the reason for the recently published textbook GaN Transistors […]
Podcast: Platform to design and build custom embedded computers
Designed for customers who want a device tailored to their specifications, without the cost of conventional electrical engineering, layout and manufacturing, Geppetto is a complete system for building and ordering custom embedded computers without the need for extensive knowledge of electrical engineering. Combining powerful web applications with Gumstix’ own manufacturing capabilities, reduces the process of […]
Podcast: Digital Controller Technology for Solid-State Lighting
Ikon Semiconductor’s integrated circuit (IC), for the dimmable LED retrofit market, is designed to meet cost and performance standards for today’s LED lighting products, while enabling greater design simplicity for bulb manufacturers and OEMs. Its IC solutions match the efficiency of comparative two-stage architectures, but with up to 25 percent fewer components. With broad dimmer […]
National Instrument’s General Purpose Inverter Controller
National Instruments expert Brian MacCleery, Principal Product Manager for Clean Energy Technology, discusses its General Purpose Inverter Controller (GPIC), digital energy revolution and how energy is moving from analog to digital, and the possibility for engineers to develop more energy-efficient systems. NI’s Single-Board RIO GPIC has been selected by the SmartPower Stack Consortium, as the […]
