October 29, 2020, after seven months of silence due to a major upgrade of the 70-meter-wide radio antenna located in Camberra, NASA sent a set of commands to the 43 year-old spacecraft, Voyager 2 that has travelled billions of miles from earth since its launch in 1977. Voyager 2 acknowledged it had received the call and executed the commands without any issue. Interesting for sure – but what is the significance of this to power engineers?READ MORE
From the very early days when power electronics equipment utilized vacuum tubes, power engineers have been concerned with energy efficiency, power optimization and how to make power supplies more reliable, smaller and smarter. Probably few of us remember the introduction of the Thyratron or the 1925 patent by Julius Edgar Lilienfeld for the Field Effect Transistor (picture 01 – picture 02), but the electronics industry is full of amazing inventions and innovations all contributing to achieving the mythical 99% efficiency level.READ MORE

Safety regulations have been in place for decades in the power industry and as we know only too well, have been through lots of revisions. And although each revision has made them more stringent and tailored to our businesses, frustratingly we have become familiar with designing products to conform to latest versions. So why do safety authorities change things that have been in place for so many years?
This is a question we hear so many times from power designers and without knowing the history and background it would be difficult to understand the motivation for IEC/EN 62368-1. Indeed, the transition from a well-established 1952 standard to something fundamentally different requires some explanation, which this article is about.
Cosel Co, Ltd today announced the addition of four new series of open frame, low profile, compact power supplies covering the range of 30W to 100W and UL/EN62368-1 certified. The LHA30F, LHA50F, LHA75F and LHA100F complement Cosel’s existing, leading LHA150F and LHA300F models, now offering an efficient power solution from 30W to 300W for demanding […]READ MORE
