ABB has created a liquid cooled synchronous reluctance motor series that achieves IEC international efficiency class 5 (IE5). It brands its synchronous reluctance motors ‘SynRM’, and is offering liquid-cooled versions across 37 to 710kW (400V in IEC 200-315 frame sizes (aluminum, steel on request). “A major advantage of the IE5 SynRM liquid-cooled motors is that they are much more efficient ...

Rohm has added a lineup of 600V super-junction mosfets in 6.5 x 7 x 1.66mm SOT-223-3 packaging. “In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact mosfets that are essential for switching operation,” said the company. “Generally, however, it has been difficult ...

Novosense Microelectronics has created a pair of isolated digital input chips suitable for 24V industrial control applications that only need power on the output side. 4-channel NSI8604 (SSOP16 package) and 8-channel NSI8608 (SSOP20) provide input/output isolation when converting voltages in the range of -60V to 60V to logic signals. (The third digit is a capital ‘i’, not a numerical ‘1’). ...

Advantech has announced a fan-less edge computer for kiosks and robotics, built around Intel’s 12th and 13th generation Core ix desktop processors up to 35W. ARK-3533, as it will be known, measures 200 x 75 x 215mm and workd from 9 – 36Vdc/ It “has a shock-resistant design that can also withstand temperatures from -20 to 60°C,” according to the ...

Teledyne has introduced a high-voltage connector system for use up to 13.5kV and 70,000 feet (21km) altitude. Called DHM, they use the company’s self-contained ‘Hi/Mate’ inserts, pre-wired inside sub-D housings and back-shells – they are only available made-up onto cables. “These inserts leverage Teledyne’s advanced interface sealing system, rendering them suitable for a wide range of aerospace and defense electronic ...

SemiQ will be exhibiting its 1.2kV SOT-227 silicon carbide mosfet power modules at APEC, the Applied Power Electronics Conference, at the end of February. The modules come with or without a co-packaged Schottky diode, with current ratings between 30 and 113A, and on-resistance spanning 80mΩ to 20mΩ respectively (see table). The SOT-227 package is designed to be bolted to a ...

Aaeon is aiming at robotics with a mini-PC built around Intel’s Core i3-N305 or Processor N97 CPUs, “chosen due to their balance of power consumption and performance”, it said. “The platform provides the sensor data processing, integrated graphics and resources required for path planning and control algorithms needed to bring automated guided vehicles and autonomous mobile robots to market.” Xtreme ...

Allegro MicroSystems has created an isolated gate driver IC for GaN power transistors that has no need for high-side bootstrapping nor the provision of a secondary side drive supply voltage. Instead, a dc-dc converter within AHV85111 produces secondary-side dc power rails – one positive and one negative – to provide gate drive power from a 12V supply (10.8 – 13.2V) ...

Würth Elektronik has introduced two families of surface-mount multi-channel galvanic isolators for digital signals. Devices in the WPME-CDIP family have four 100Mbit/s isolated channels and a built-in dc-dc converter that provides isolated power from one side to the other. Different versions have different combinations of digital isolator directions: all from input to output, three in that direction and one returning, ...

Advantech has used AMD Ryzen Embedded 7000 processors in a series of industrial ATX motherboards dubbed AIMB-723. “This is the first industrial-grade motherboard integrated with the AMD B650 chipset, delivering high computing performance with a seven-year lifespan,” said Advantech. “It stands out as the first AIMB motherboard to embrace DDR5 UDIMM, as well as support up to a three-slot discrete ...
