Application note: developments in battery stack voltage measurement download

Linear TechnologyWed, 30 Jul 2014

Automobiles, aircraft, marine vehicles, uninterruptible power supplies and telecommunications hardware represent areas utilising series-connected battery stacks. These stacks of individual cells may contain many units. In such systems, it is often desirable to accurately determine each individual cell’s voltage. Obtaining this information in the presence of the high ‘common-mode’ voltage generated by the battery stack is more difficult than might be supposed.

White paper: IEC 62310 for static transfer systems — ensuring performance and safety download

Socomec UPSTue, 22 Jul 2014

Before the IEC 62310, prior to 2008, there was no product standard for the ‘static transfer system’ (STS). The closest standard used by manufacturers was the IEC 62040 (uninterruptible power systems, or UPSs). Indeed it is a good reference, but the weak points are definitions and tests. This paper from Socomec explains why users should ask for IEC 62310-compliant STSs.
