STMicroelectronics Eases Design of Advanced Energy-Saving Power Supplies with Eco-Certified 400W Evaluation Board Updated On Sat, Aug 29th, 2020 by Saurenergy STMicroelectronics’ EVL400W–EUPL7 evaluation board delivers a ready-to-use 400-Watt power-supply solution that meets today’s toughest eco-design norms. The board leverages innovative features of ST’s L4984D current-mode PFC controller and L6699 resonant half-bridge controller to maximize energy efficiency in multiple operating modes. Full-load efficiency is over 93% at 230VAC and over 91% at 110VAC, with no-load mains consumption of […] Read more
STMicroelectronics Reveals Fast-Starting Intelligent Power Switches for Demanding Safety Applications Updated On Wed, Aug 26th, 2020 by Saurenergy STMicroelectronics has added new fast-starting devices to its family of intelligent power switches for safety-instrumented systems. With power-on delay time of less than 60µs, the IPS160HF and IPS161HF satisfy standardized requirements for interface types C and D in Safety Integrity Level (SIL) Class 3 applications. Featuring a wide input-voltage range of 8V-60V, maximum switch resistance (RDS(on)) of […] Read more
Largest Solar Power Study to Date Discovers 25% Power Loss Updated On Mon, Nov 12th, 2018 by Saurenergy RESEARCHERS at the University of Huddersfield have undertaken the largest study to date into the effectiveness of solar panels across the UK and discovered that parts of the country are suffering an overall power loss of up to 25% because of the issue of regional ‘hot spots’. Hot spots were also found to be more […] Read more
This solar-charged battery directly stores energy from sunlight in a tank Updated On Sat, Sep 24th, 2016 by Saurenergy Researchers at University of Wisconsin–Madison have developed solar-charged battery that directly stores energy from sunlight in a tank. Song Jin, a professor of chemistry at the University of Wisconsin–Madison, has integrated the solar cell with a large-capacity battery. He and his colleagues have made a single device that eliminates the usual intermediate step of making […] Read more
