Puls Power has introduced DIN-rail power supplies for railway applications, suitable for both track-side and on-board train equipment. The firm claims 100% greater mains failure bridging time than required by the railway standard EN 50155 (S2). All PCBs are conformally coated to increase weather resistance, and all PSUs are completely convection cooled for increasing reliability, ...

Texas Instruments has announced ready-to-use 600V gallium nitride (GaN) power transistors with built-in driver stages. The 50 and 70mΩ devices are intended for applications from 100W up to 10kW. While GaN transistor have the potential to increase the efficiency and shrink the size of power supplies, their high speed and somewhat fussy characterisitcs mean that ...

Renesas is aiming at industrial robots by adding support for DDS-XRCE (data-distribution service for extremely resource constrained environments), one of the protocols planned for the ROS 2 communication standard. Specifically an XRCE-DDS client (‘Micro XRCE-DDS’ from eProsima) has been implemented on Renesas’ 32bit RX65N MCUs. “Robot Operating System – ROS – is a key framework ...

Aiming at automotive, Rohm has introduced a buck-boost dc-dc chipset, claimed to provide the lowest current consumption with good transient response for ECUs (electronic control units) for cluster panels and gateways used in start-stop vehicles. Unusually, one of the chips (BD8P250MUF-C) is a buck converter, and the other (BD90302NUF-C below right) is a totem pole ...

An MIT survey has revealed global ethical preferences when it comes to autonomous vehicle safety, and some regional variations. Over 200 million participants from over 200 countries quizzed themselves on versions of a ‘trolley problem’ ethical dilemma – where the vehicle must opt for one of two potentially fatal options in an impending accident – ...
