Duo of isolated eighth-brick DC/DC converters deliver on efficiency
A pair of DC/DC converter modules in eighth-brick formats has been launched by Ericsson, which are able to handle currents of up to 40A and deliver world-leading efficiency. Enabling reduced energy and cooling costs, these two modules are the most efficient 40A-class eighth-brick-format power modules in the industry: the PKB4211D and PKB4110D deliver respective efficiencies of up to 95.3% and 94.7%, with tightly regulated 5 and 3.3V outputs ...
Meeting needs for digital solutions in the power industry
After seeing a gap in the market, former ABB colleagues Eitan Frankental and Magnus Lindström, started GridZupport with ABB veteran Carl-Johan Linér. The company develops digital solutions that coordinate information for power stations. This gives the customer a better overall picture, safer operation and increased productivity – all which contribute to a sustainable environment.
Networked electronics need high performance batteries
The wearables market is increasing rapidly worldwide, whether you think about smart watches or fitness trackers, they are all growing at a rate no one expected. Batteries are a strategic component of these devices. VARTA Microbattery will be presenting its products and solutions at this year’s IOThings in Milan, from 16th to 17th May, 2017.
Linear LED drivers increase efficiency in LED strips
The constant current regulators introduced by Diodes Incorporated, BCR401U, BCR402U and BCR405U, are appealing to lighting designers as they enable simple driving of low-current LED strips and panels in the commercial and industrial lighting sectors. Targeted at 12 and 24V linear LED strips, these regulators increase light output efficiency as they only require a 1.4V supply, allowing more LEDs in the string.
Integrated DC motor driver IC reduces design complexibilty
A motor driver IC designed for pulse-width-modulated (PWM) control of DC motors has been released from Allegro MicroSystems. Allegro’s A5950 is capable of peak output currents up to ±3 A and operating voltages up to 40V. This new device is targeted at the automotive market with end applications to include heads-up-display, shift drive, door closure and engine thermal management applications.
AC/DC medical power supplies offer up to 95% efficiency
The new wide input range, single output PQC series of industrial/medical power supplies has been announced by Murata Power Solutions. Rated at 250W of output power, and packaged in an industry-standard open frame 3x5”, 1U footprint, this high-efficiency design can deliver its full output using convection cooling when operating in temperatures up to 50°C.
Supercapacitors vs. batteries.
Based as a follow on from the IDTechEx overview, ‘Supercapacitor Technologies and Markets 2016-2026’ the report ‘Supercapacitor Materials 2017-2027’ has just been released. It is packed with detailed analysis, many new infograms, conference slides, roadmaps and a ten year forecasts 2017-2027. It is based on global research by PhD level multi-lingual analysts mainly in 2016-7 with frequent updates.
LED Drivers series extended with 320W output power
The new LNE-320W model has been added to the constant current/constant voltage LNE series of LED Drivers from Delta Electronics, which have an output voltage of 12, 24, 36 and 48V. The single output product comes with different combinations of features to suit different application requirements and energy optimisation needs.
High current inductor handles extreme environments
A new IHLP low profile, high current inductor has been introduced by Vishay Intertechnology. It comes in the 1616 case size that combines a high operating temperature to +155 °C with a low profile of 2 mm for commercial and industrial applications in extreme environments.
Revisiting power consumption in home appliances
The notion of smart home has been making headlines for many years, but it’s actually the energy efficiency part where homes are making the most tangible gains through what designers call inverterisation of appliance designs.
