Back to Basics: The Importance of Switching Frequency

Back to Basics: The Importance of Switching Frequency

The importance of switching frequency quickly becomes apparent to systems designers bringing regulated power to on-board semiconductor devices. With the continual demand for higher performance, CPUs, DSPs and other such devices grow more power-hungry. Accordingly, higher power density regulators with minimal PCB footprints have evolved; these use the latest in IC integration, MOSFETs and packaging. However, even these struggle keep pace with the continuing stream of newer, more powerful devices. With these pressures, it is tempting to increase regulator frequency, as this reduces the size and board footprint requirements of the associated passive devices...

Stephen Oliver to present at IEEE Smart Tech Metro Area Workshop, Boston

Stephen Oliver to present at IEEE Smart Tech Metro Area Workshop, Boston

The two-day IEEE Smart Tech Metro Area Workshop for the Boston area offers an interesting range of all-day and half-day sessions around some of the most innovative, impactful technology in the region. The tracks include smart grid, computer technology, life science and biotechnology, robotics, renewable and harvest energy, among others.  To quote the IEEE directly, “Learn first-hand from the field experts. Each workshop is a springboard to a deeper understanding of technology and its myriad applications and potential for innovation.”

Optimizing for Datacenter Power System Efficiency and Reduced Energy Costs

Optimizing for Datacenter Power System Efficiency and Reduced Energy Costs

There are no sloppy designs in datacenters. To the consumer a datacenter is just another pipe in the cloud, a conduit for their data and experiences.  However, to the industry giants wringing real dollars (in the form of demographic studies, transactional charges, and raw click-based advertising) a datacenter is the backbone of their business operations. Just like the assembly lines of Ford and the coke furnaces of Carnegie, the most efficient (least cost to operate) datacenter provides the greatest set of financial and operational benefits to their owners.

Back to Basics: What is Active ORing?

Back to Basics: What is Active ORing?

The uninterrupted availability of server, communications and telecoms equipment is frequently critical to its client applications, so this equipment typically uses two or more power sources in a redundant power architecture. These sources need mutual protection, otherwise a short-circuit fault in one could quickly overload and damage the others.

Do We Need a Definition of Power Management?

Last month we invited you to participate in a poll about power management and power conversion. Several readers participated, and the results were very interesting. Everyone who responded was involved in power conversion, but half also have to design hardware for parts of your application other than the power system.
