Power System Apocalypse

Power Channels: Batteries and Portable Power, Communications Power, Smart Grid Power, Switch-Mode Power

Whenever anyone uses the words, “the end of…” I both notice and smirk. Many things end eventually (I was reading about the “end” of the IBM Selectric typewriter today, for instance), but proclaiming the end of something before its time makes me pause and doubt. One that has me thinking, however, is: “FCC considering exploring ‘end dates’ for the PSTN.” This sounds eerily like a telecommunications apocalypse, where people have to examine their core beliefs and decide what side of the wireline/wireless fence they fall.

The telecom prophecy comes from the Technical Advisory Council (TAC) to the Federal Communications Commission (FCC), delivered in June, 2011. The Working Group made certain recommendations to the FCC, who must now decide what to do. It’s never easy being given predictions that can drastically alter the future, particularly ones that affect the entire communications infrastructure. TAC was very clear about its suppositions, however.

The following points were presented to support the “erosion” of the PSTN (public switched telephone network – what the entire US wireline network is based on):

• By 2014, the United States will have fewer than 42 million access lines.

• By 2014, US consumers will have 31.6 million Voice-over-IP (VoIP) lines, accounting for 42.5% of all US access lines.

• More than 25% of US consumers aged 18 or older have already given up their voice landline for voice wireless-only service.

• By 2018, only 6% of the US population is expected to be served by the legacy PSTN.

Consumer preferences are remarkably fickle, so one of the more important statements made by TAC is, “The transition will be driven by when government subsidies to the PSTN end.” Indeed, the economic impact was one of the major points addressed by the “Critical Legacy Transition Working Group.” Critical legacy transition sounds rather ominous.

Energy Efficiency with Class D Amplifier Modules

Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure

Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
