Cambridge GaN power drive start-up QPT has recruited an advisor to its board: electric motor and business specialist Simon Hart, who “holds C-level roles at several technology companies”, according to QPT, and is entrepreneur in residence at the University of Nottingham. “Nothing excites me more than finding a British innovation and then helping the company on its journey to bring ...

Cambridge GaN Devices (CGD) has teamed up with Qorvo to build a GaN-based evaluation kit for controlling brushless-dc and permanent magnet synchronous motors. From Qorvo comes its PAC5556A motor control IC that combines a 150MHz Arm Cortex-M4F processor and 128kbyte of flash, with 600V gate divers, PWMs and multi-chanel data conversion. CGD is providing its IC-based GaN power hemts that ...

Drive System Design (DSD) and Alvier Mechatronics have teamed up to create a development platform for electric vehicle drives. “The project leverages DSD’s expertise in rapid development engineering and Alvier Mechatronics’ experience in novel manufacturing methods for high-volume applications, material know-how and electromagnetic design,” according to DSD. Called iDS, it “showcases technologies, materials and analysis techniques with real, tested hardware for ...

Raspberry Pi has released the official M.2 HAT+ for Raspberry Pi 5, allowing the connection of NVMe memory drives and AI accelerators. It accepts M.2 2230 or 2242 form factors, to which it can supply up to 3A and transfer data at up to 500Mbyte/s via the Pi’s single PCIe 2.0 channel. Being compliant to the HAT+ specification means that ...

AMD has introduced a motor driver starter kit for its Kria K24 system-on-module – which is built around a Zynq UltraScale+ IC and measures 60 x 42 x 11mm. The kit, called KD240 drives starter kit, includes the module, a carrier card and a heat sink. Included is 2Gbyte (2chan x 256Mbit x 16bit/chan) of LPDDR4, and a 512Mbit QSPI ...

To meet Open Compute Project (OCP) requirements, Molex has created a connector system that combines low-speed signals, high-speed signals and power into a single cable assembly. The “data-center product development team collaborated with the power engineering group to optimise power-contact design, thermal simulation and power dissipation”, according to the company. Inside is up to 4A can be carried alongside 10 ...

Renesas Electronics has teamed up with electric motor maker Nidec to develop a 6-in-1 e-axle for electric vehicles. E-axles combine motor, inverter and gearbox into one unit and, according to Renesas, are beginning to collect other power electronics functions such as dc-dc converters and on-board chargers to form a convenient package for car makers to integrate – an idea dubbed ...

Rohm is aiming at motor drives operating on 24, 36 or 48V with n-channel mosfets rated at 40, 60, 100 or 150V to give some leeway for spikes and noise. There are two series with 13 devices all-told: nine in 5x6x1mm HSOP8 (below left) packaging called RS6xxxx, and four in 3x3x0.8mm HSMT8 packaging called RH6xxxx, with current ratings between 25A ...

EPC is aiming at eMobility, forklifts and high-power drones with a 150Arms brushless motor driver design using its GaN power transistors. Documents for EPC9186, as it will be known, are not available yet, but the company promises operation from 14V to 80V for “applications such as electric scooters, small electric vehicles and agricultural machinery” in addition to the items above. ...

Telford-based iconsys has a contract to deliver variable speed motor controllers and other equipment to an un-named company for an un-named marine application. Described as “around 30 variable speed drives” by ABB, whose drive cabinets are being supplied, they are to be joined by drive-trains, programmable controllers, sub-sea connection boxes, sub-sea motors and gearboxes, said ABB. It includes the installation ...
