460W of regulated dc is available from a 76 x 127 (3 x 5inch) footprint open frame power supply, which can also deliver 340W without forced air cooling, thanks to its 94% efficiency. Called DDP460 series and made by Enedo Power, it comes in 24, 48 and 56V output versions – samples are available of these – and with 12 ...

Rohm has developed its 4th generation 650V fast recovery diodes (FRDs), balancing forward voltage and reverse-recovery time for high-power industrial and consumer equipment including air conditioners and electric vehicle charging stations. RFL series (right) is nominally low forward voltage and reduces Vf by ~3.2% and trr by ~8.3% compared with the existing RFN series. RFS series (right), nominally high-speed, reduces ...

TDK has introduced 7.5kW DSP-controlled programmable power supplies that are 1U size for rack mounting. Part of the company’s Genesys+ series of PSUs, there are six models: 0 – 20V 375A, 0 – 40V 188A, 0 – 100V 75A, 0 – 150V 50A, 0 – 600V 12.5A and 0 – 1.5kV 5A. Update: TDK later in-filled these options with six ...

Ofgem has granted Irish company MaresConnect an interconntector licence to own and operate a 245km 750MW dc link between Wales and Ireland. The under-ground and under-sea interconnector, a twin-cable high-voltage set-up also called MaresConnect, will link the power markets of Ireland and Great Britain, between EirGrid’s Maynooth 220kV sub-station west of Dublin and a 400kV National Grid Electricity Transmission substation ...

With global demand for EVs growing at pace, the race is on for battery innovators to avert a supply crisis due to shortages of various elements found in the earth’s crust, such as nickel, cobalt and lithium, writes Ben Palmer, a partner and patent attorney at Withers & Rogers. Diminished availability of these much-needed raw materials, combined with growing concern ...

Component distributor Anglia Components has signed an agreement with Alexander Battery Technologies (ABT), a UK-based manufacturer of custom battery packs. This is the first distributor that ABT has appointed – Anglia will be its exclusive distribution partner in the UK and Ireland. The County Durham-based battery maker offers custom battery packs, including lithium-lon, NiMH and primary cell packs, for OEM ...

At Embedded World 2022, we caught up with Thomas Rottach of Siglent Technologies, as part of our promotional coverage for the event. This is the first official presentation of its newly introduced 12-bit oscilloscope. With this, Thomas tells us, Siglent moves up in performance and deliver more benefits to its customers, with the high vertical resolution enabling developers to see ...

CorPower Ocean of Sweden has unveiled its first commercial-scale wave energy harvester and a concept for supporting wind turbines. The harvester, dubbed C4 and rated at 300kW, will ultimately form part of HiWave-5 Project, a wave array off the coast of Aguçadoura, Portugal. The buoys are 19m tall and 9m in diameter. Inside the thin buoyant structure (see cross section left) is ...

Vishay Intertechnology has introduced a series of surface-mount bidirectional transient voltage suppressors in SMC (DO-214AB) packaging for automotive, industrial and telecom use. Surge capability is 3kW at 10/1,000μs to meet the specifications of ISO 16750-2 Pulse b. Called the SMC3KxxxCAHM3_A series, leakage current can be as low as 1μA from 22 to 120V, and operatioj is up to 175°C. For high reliability, ...

Boundaries are being pushed in all engineering sectors, but few more so than with regards to power electronics. Matt Brown and Andy Longford, of Inseto and PandA Europe, explain. For every problem solved in the power semiconductor industry, it seems that at least one other is introduced. Where performance is concerned, the goals are typically to increase power density and to ...
