An agreement between Components Bureau and Artesyn covers the UK and Ireland, adding the latter’s high power modular and programmable power supplies to the distributor’s range, which includes AC/DC power supplies and DC/DC converters from a selection of manufacturers. Artesyn’s power offering ranges from products of 3W to hundreds of kW, for use in a variety of power supply control ...

Claimed to be the industry’s first fanless 1kW modular power supply, the COOLX1000 from Advanced Energy is now available from Relec Electronics. It is designed for operation in sensitive environments, such as medical and scientific applications. The power supply measures 6.5 x 10-inch (165 x 254mm) and is 1U high. The U-channel design is based on patented, resonant technology. It ...

Georgia Tech is to develop circuit breakers for >1MW dc power links up to 100kV – with wind farms, electric aircraft and electric ships in mind. Direct current power transmission is more efficient than AC (see below), but high-power dc is far harder to interrupt than ac – there is no current zero crossing in which to switch and plenty ...

Low clamping voltage, high surge transient voltage suppressors (TVS) from Alpha and Omega Semiconductor (AOS) are designed for Vbus protection. The AOZ8621UNI series of six TVS are suitable for USB Type-C Power Delivery (PD), in laptops and smartphones and any application using the PD protocol that can deliver up to 100W. The series covers a reverse working voltage (VRWM) range ...

Cheltenham-based design company Duku has developed a pop-up electric vehicle charge point, claiming it to be a world first. Six of them are on trial in Oxford. A pop-up design was adopted to reduce street clutter, but the amount of historical architecture and utilities under Oxford pavements meant minimal available underground space. “It’s an absolute mess below the pavement in many ...

Orbital Marine Power has taken another step towards installing its 2MW floating tidal turbine off Orkney, by engaging Faun Trackway to manufacture the four steel anchor structures, plus bespoke mooring connectors, at Faun’s facilities on Anglesey. The turbine, called O2, will be installed in the Fall of Warness where Orbital has an existing berth, and a grid connection with the Orkney-based European Marine ...

Commeo’s eponymous energy storage blocks build into systems with up to 1MWh capacity, intended to power mobile robots or protect the power supply of industrial plants and factories by buffering or providing emergency power. Each cube has a length of something over 20cm and contains multiple layers of lithium-ion cells with its own battery management system. These are aggregated into ...

Varta has added three smaller button cells to its CoinPower range of Li-ion rechargeable batteries for hearables, other wearables, and other portables. “The provision of energy in a tiny space is playing a growing role in an increasing number of aspects of modern mobility and health,” said the firm. “This is the case with hearables, which are worn on or ...

Liquified gas electrolytes could be the key to batteries that use lithium metal anodes, according to the University of California San Diego. Replacing the carbon anode of lithium-ion cells with metallic lithium could theoretically improve energy density in rechargeable batteries, but they have not become popular because the inclusion of metallic lithium makes the batteries unsafe – particularly as the ...

Power Integrations created an isolated gate drive system for up to four paralleled 1.7-4.5kV power modules – either IGBT or silicon carbide mosfet. Called Scale-iFlex, it is dual channel so, for example, independent control of high and low-side switches in a half-bridge is possible. “The system is optimised for the latest 1,700V to 3,300V rated power modules from all of ...
