Attaining power efficiency in data centers

This technical article examines the key benefits and metrics of Samsung's Green DDR3 technology.

How to achieve high efficiency with power switches

In general, high frequency operation allows the use of small-sized passive components in switch mode power supplies (SMPS), while it causes switching losses to increase in a hard switching mode.

Solving the VoIP power supply problem

A power supply for VoIP phones is extremely cost-sensitive, power-loss sensitive and needs reasonable cross regulation. The C'uk converter excels in this application.

Use active PFC to boost motor efficiency (Part 2)

There is tremendous potential for worldwide energy savings in the current trend to upgrade electric motors and motor controllers.

Protecting components from ESD damage effects

Protecting components from the effects of ESD damage begins by knowing how they can be damaged and their level of sensitivity.

CFLs with improved PF

NSK8700 asks: "What is the the switching frequency of CFL inverters and how is this fixed? Can anyone provide a circuit schema for a CFL switcher?"

Biofuel prep

Joller replies: Dry algae factor is the percentage of algae cells in relation with the media where it is cultured, e.g. if the dry algae factor is 50%, one would need 2 kg of wet algae (algae in the media) to get 1 kg of algae cells."

Making battery chargers
greener

Battery chargers of CE devices stay plugged in all the time, humming away at standby power consumption. Here's how you can make those chargers "greener."

Simplifying stability checks

This application report explains a method for verifying relative stability of a circuit by showing the relationship between phase margin in an AC loop response and ringing in a load-step analysis.
