EDN: Meeting the power demands of battery supplied automotive electronics

Meeting the power demands of battery supplied automotive electronics

Have you driven a new automobile recently?  It can be an almost futuristic experience, with sophisticated gauges, touch screens, connected entertainment systems, and lighting—all of which need power. Behind all these electronics are battery regulators and battery chargers that manage the power both into and out of 12V, 24V, and 48V batteries. Each year the ‘must have’ list of supported accessories and electronic systems grows with the expectation that the size, weight and number of supporting power components will keep pace with the increased power demands.

Electronic Products: PCIM 2017 in a nutshell

PCIM 2017 in a nutshell

It was the year that saw the evolution of wide-bandgap technology and its uptake by design engineers into actual products. Yes, there are concerns that SiC is more expensive at the device level than Si but that’s not true at the system level when the frequency is increased from 10 kHz to 40 kHz, according to Infineon. Automotive appeared to be the primary target for most wideband gap devices, but certainly there were plenty of products that targeted photovoltaics, EV charging, traction control, and motor drives.

EDN: Data center next generation power supply solutions for improved efficiency

Data center next generation power supply solutions for improved efficiency

“Ok Google: How do I power a Data Center?”

Claude Shannon started it all when he wrote "A Mathematical Theory of Communication" in 1948 in which he reduced the communication of information to 1s and 0s, essentially binary digits. That theory led to the ability to transmit data without error in the noise-filled environment of the real world. Shannon would have been 100 years old on April 30, 2016.

EDN: Top 10 must-have innovations for power designers from APEC 2016

Top 10 must-have innovations for power designers from APEC 2016

In this slideshow, I will be providing power designers with, what I consider, the top 10 new innovative products and architectures announced at APEC 2016. I view these following slides as essential to designers for near-term design needs as well as additions to a designer’s portfolio for future designs. Please watch for in-depth technical articles on these 10 items in the coming weeks authored by me on EDN.

Electronic Design: APEC Opens with a Blizzard of Product Disclosures

APEC Opens with a Blizzard of Product Disclosures

After the past couple of months, the term “blizzard” may trigger some post-traumatic shivers. However, engineers can quickly warm to the torrent of product announcements made at this year’s IEEE Applied Power Technology Conference, which opened Monday, March 16, in Charlotte, N.C.
