The use of power supplies in harsh, remote environments brings with it many fundamental design issues that must be fully understood if long-term reliability is to be attained. For designers of communications equipment downtime is not an option. Both revenues and safety can be compromised under such circumstances.

The digital signage market is experiencing rapid growth. Organizations across a wide range of industries are making large investments in the content, source machinery and displays that comprise digital signage systems. The choice to protect these investments from power problems is crucial—yet frequently overlooked....
The need to respond to changing market standards in a compressed time to market window has led to the widespread use of programmable logic devices (PLDs) in a broad range of consumer applications. While development of application specific integrated circuits (ASICs) and application specific standard parts (ASSPs) requires...
For a majority of applications implemented today, the Intermediate Bus Architecture (IBA) has become the preferred power architecture. This power architecture has led to the development of the isolated, semi-regulated DC/DC converter known as the Intermediate Bus Converter (IBC).
IBCs are an improvement to the standard...
Cooling fans consist of an aggregate of airfoils, i.e. blades positioned around a hub that is driven by an electric motor. Due to their airfoil nature, a pressure differential is required across the blades to create the required flow. Therefore, if this pressure differential is disturbed, fan will suffer performance degradation. ...
Lithium-ion batteries, like other battery types, are subject to a process of wear and tear during charging and discharging due to chemical changes.
Without battery balancing, the weakest cell in a multicell battery always determines the capacity of the entire system. However, since individual cells age differently,...
With the digital expansion over the past few decades, new requirements for data centers to store, transmit, and manage data of all sorts are reaching a critical level.
In this article, GE power discusses the path to improving efficiency as it applies to AC-DC power supplies (AC-DC front ends) within server equipment....
Using electrostatic technologies in supercapacitors rather than the electrochemical technology of battery cells provides another level of control and reliability for all kinds of power sub-systems, overcoming the limited lifetime of batteries, particularly in industrial and transportation applications.

To ensure the stability of voltage regulators and switched mode power supplies, the control loop behaviour must be measured and characterised. A well compensating voltage controller enables stable output voltages and reduces the influence of load changes and supply voltage variations. The quality of this control circuit...
The size or power density of a power supply is a key criteria when selecting the optimum product for a given application. In applications where fans are not desirable due to noise or reliability concerns then efficiency becomes of primary concern. Power supply technology has evolved to a point where efficiencies in the...
As power levels for board components have risen, thermal engineers have been forced to design larger and more innovative heat sinks than ever before. Along with the thermal challenge has come the mechanical challenge of attracting these heat sinks to the components in a reliable fashion.
There are many traditional...
