Optimize a Power Scheme for these Transient Times
A variety of mix-and-match modules allows designers to adapt to multiple energy sources and load requirements for power subsystem targeting pulsed-RF applications that demand high transient response to the load current waveform.
+48 Is The New –48
Tight tolerance +48-V (nominal) power distribution allows systems to qualify as SELV designs, reducing installation and operating costs. Narrow-range 48-V rails facilitate high-efficiency power converters to power line cards and processors.
Reversible Power Improves Versatility
Most system designs contemplate power flows in one direction only: from source to power-management blocks to loads. Some types of systems, however, benefit from power-management blocks capable of bi-directional power flow.
The Hard Facts On Soft Switching
For many, a good rule of thumb for switch-mode power designs has been that hard switching is easy, and soft switching is hard. Power-switching technology developments, however, give reason to switch thumbs.
Next-Generation Servers Require Robust Power Platforms
Market forces drive incremental data-access and computing costs down with increasing use. In server environments, this means that processing efficiencies and densities must increase throughout the system-design hierarchy, from core to cabinet and beyond to the data center infrastructure.
Tap Online Design Tools To Improve Your Power Subsystem Designs
Vendor-provided online design tools allow engineers to start developing and evaluating designs quickly, gaining critical insights into design alternatives and engineering tradeoffs, even in advance of sampling major power components.
Move Thermal Issues To The Front Of Your Design Cycle 1
An effective design must consider the big picture of power needs, thermal dissipation, and overall packaging, and do so early on.
400-V DC Power Transformation Saves Upfront “Green” Supply Costs 3
Vicor's Stephen Oliver makes the case for 400-V dc power as the first stage in power distribution in an intermediate bus architecture for telecommunications and the data center.
Take A Multifaceted Power Approach To Reduce Your UAV’s Weight 1
UAVs (Drones) have multiple power buses and a need to minimize weight, including in power management electronics. Vicor's Stephen Oliver considers alternative topologies.
High-Voltage Busing Makes Sense
There are two conflicting ways to increase power-distribution efficiency in data centers as electricity flows between the front-end voltage converter and the ICs on blade servers. One is to lower the bus voltages around the circuit board. The other i

How to Outsource Your Project to Failure 3

This article will address failure to carefully vet a potential manufacturing or “turnkey” partner and/or failure to transfer sufficient information and requirements to such a partner, a very common problem I have seen again and again with my clients over the years, and have been the shoulder cried upon by several relatives and clients in the past....More

Transition from the Academe to the Industry Unraveled 1

There have been many arguments here and there about how short-comings of universities and colleges yield engineers with skill sets that do not cater to the demands of the industry. There have been many arguments here and there about an imminent shortage of engineers lacking knowledge in the sciences. There have been many arguments here and there about how the experience and know-how of engineers in the industry may vanish due to the fact that they can’t be passed on because the academic curriculum deviates from it....More

Small Beginnings 5

About 10 years ago I received a phone call from an acquaintance. He had found a new opportunity selling some sort of investments and he wanted to share it with me in case I was interested. Ken had done fairly well for many years as a contract software developer primarily in the financial services sector. His specialty was writing RPG code. (RPG is often referred to as a write only language.) But he was seeing the handwriting on the wall as the industry moved on to other methods, and saw himself becoming a fossil....More
