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 ...
Lithium-carbon dioxide batteries have theoretical promise, including in aviation where the lightweight materials are desirable – it might might make good use of Mars’ 96% CO2 atmosphere, for example. Headline figures are a theoretical specific energy density of 1,876Wh/kg and a ~2.8V discharge potential, but in practical terms the technology has not even reached infancy. To build a solid foundation for its development, a ...
There will be a new player in the dynamic silicon photonics sector, as Synopsys and Juniper Networks announce a partnership to form a new, separate company, with Synopsys as the majority owner. As yet, unnamed, the company will offer an open silicon photonics platform (integrated lasers, optical amplifiers) and photonic components. The companies believe that this platform will lower the ...
The CBI series of DC-UPS helps power system designers meet tight power budgets by intelligently managing the available power between the load and the battery, explains John Stone, Sales Director, Relec Electronics. Adel Systems has developed an integrated power solution, with diagnosis, back-up internal power sharing and the MODbus communication protocol. Today’s smart cities require a range of information and communications ...
GaN Systems is claiming “the world’s smallest 65W and 100W GaN chargers” at APEC this week. Made with power design company Rompower, the 65W charger is 30.5 x 35 x 46.6mm (21.4W/in3). Peak efficiency is ~94.5% (115Vac) or ~95% (230Vac). For the 100W unit, GaN Systems has given four dimensions: 28.6 x 44 x 35 x 67mm (Electronics Weekly has asked ...
NXP and Hitachi have co-designed a gate driver evaluation board for Hitachi’s 1.2kV RoadPak SiC mosfet half-bridges. The half-bridges are ~75 x 70mm and come in 580, 780 and 980A versions which are liquid-cooled – one side having a pin-fin array (just visible right) which has to be sealed into a water-glycol filled cooling manifold. Junction to fluid resistance is typically ...
A low-noise dc-dc converter and a low-noise LDO are debuting on TI’s APEC stand, alongside an 11kW 800V GaN three phase inverter design. LMQ66430 is a 36V 3A buck converter that includes two input bypass capacitors and one boot capacitor and includes the company’s ‘dual random spread-spectrum’ jittering technique, “enabling engineers to easily meet CISPR 25 Class 5 EMI standards while offering 1.5µA ...
