600V Super-Junction mosfets for bridge and ZVS converters

STMicroelectronics’ DM6 600V mosfets contain a fast-recovery body diode to bring super-junction technology to full-bridge (and half) phase-shifted zero voltage switched (ZVS) converters – and other applications that need a robust diode to handle dV/dt. “Leveraging ST’s carrier lifetime control technology, the mosfets have reduced reverse-recovery time [trr] to minimise power dissipation in the diode ...

Halogen-free PCB material

Panasonic has introduced a Halogen-free multi-layer circuit board material Called MEGTRON6.  Its capacity and speed are suitable for  at 5G systems. There is a growing need for environment-friendly halogen-free material for circuit board materials used in communications infrastructure equipment. Conventionally, the use of non-halogen flame retardants entailed increased transmission loss, particularly in the high-frequency range. ...

Get a life, says Federico Faggin

AI is being over-promised, says Federico Faggin (pictured) who put the 4004 into silicon gate MOS, delivered the 8008 and designed the 8080 before founding Zilog and designing the Z8 MCU and Z80 CPU and then going on to co-found Synaptics with Carver Mead. “The fundamental problem is that, because of the recent successes, people ...

2D materials for lithium-air batteries

2D materials could be better catalysts for lithium-air batteries than 3D, say researchers from the University of Illinois at Chicago. “Currently, electric vehicles average about 100 miles per charge, but with the incorporation of 2D catalysts into lithium-air batteries, we could provide closer to 400 to 500 miles per charge, which would be a real ...

Talent shortage is biggest risk, says Gartner

Staff shortages are the top emerging risk which companies face, according to Gartner’s latest quarterly Emerging Risks Survey. The survey of 137 senior executives in 4Q18 showed that concerns about talent shortages now outweigh those around getting ready-for-new-data-privacy-laws and cloud computing which were the top two risks in the Q3 survey.   63% of respondents ...
