Portable electronic devices use internal batteries that need to be charged from an external power supply, most usually an AC/DC wall adapter. Li-ion battery technology has decreased the total weight of portable devices. However, a bad charge sequence can induce Li+ temperature increase, thermal runaway and burst, and endanger people’s lives. One of the primary [...]

While maximising power efficiency at full-load is a top priority in the design of an AC/DC supply, standby power considerations and new power-efficiency standards loom larger. Thus, apart from the general subject of “high efficiency,” designers are looking harder at ways to maximize energy-savings from end to end. Indeed, saving milliwatts is of particular concern [...]

How long will it run?
When power fails, many home and commercial alarm systems go to a backup battery, most commonly a 12-volt sealed leadacid type. If you’re able to accurately sense the current draw, and the battery is well-characterised, you’ll be able to accurately determine the amount of time remaining before your mission-critical system dies.
With [...]

The low cost, simplicity of design and intrinsic efficiency of flyback transformers have made them a popular solution for power supply designs of below 100W to 150W. Other advantages of the flyback transformer over circuits with similar topology include isolation between primary and secondary and the ability to provide multiple outputs and a [...]
