Lambda lifts efficiency in off-line switching supplies
Devon-based power supply maker Lambda has developed an efficiency-boosting topology for off-line switching supplies which it has included in a range of products. The patented multi-resonant-topology [MRT] that lies at the heart of the new design gives a five per cent improvement in efficiency over more traditional methods, said Lambda, while keeping frequency variations under 30 per cent in normal ...

Power density conundrums
Power density conundrumsRichard WilsonOne of the myths of electronics has been that power supply design was always the lastbit of a project to be tackled, implying that it was thrown together in haste. This mayhave once had the ring of truth about it, but not any more. High processor speeds, evermore restrictive space constraints, not to mention the trend for ...
