The Joulescope is an inexpensive test instrument designed to let developers of embedded systems get a good look at the energy and power consumption of their hardware during important events such as interrupts and wake-up sequences. Developed by a company called Jetperch, Joulescopes are about to become available through a Kickstarter campaign launching Feb. 19. […]

Sights at the IDT tech seminar
Integrated Device Technology hosted a one-day technical seminar in Detroit covering wireless power, sensing, and timing technologies. Here are some of the notable demos we saw running there. NEXT PAGE: A better way to track motor shaft position: Inductive sensing
Reference design for galvanically-isolated CAN transceiver
The R-REF03-CAN1 Reference Board demonstrates the ISO1042 isolated CAN transceiver supplied by the R1SX-3.305/H isolated dc/dc converter. To supply the reference board only one 3.3-V external supply is required. The green LED indicates the presence of the VCC2 supply on the secondary (CAN bus) side. The reference board allows designers to quickly develop and analyze […]
Eval boards check power modules for trimming, sequencing, soft starts and sensing functions
RECOM’s eval boards for the RPM‐1.0, RPM‐2.0, RPM‐3.0, and RPM‐6.0 buck regulator series generate a constant output voltage with an output current up to 6A from an external DC source. The multitude of functions offered by the RPM power modules such as trimming, sequencing, soft‐start, enable, and sensing can be evaluated. More importantly, the behavior […]
SDK for Sigfox Monarch networking includes reference designs and productivity tools
STMicroelectronics is now the first chip maker to develop and market a certified solution for seamless global, ultra-low-power, and long-range wireless IoT connectivity enabling the Monarch worldwide tracking and positioning service from Sigfox. ST’s solution lets users create region-independent smart objects that connect automatically to the local Sigfox network anywhere in the world, empowering inter-regional mobility, […]
Thermal simulation package brings CFD to autonomous electric vehicle design
New Simcenter software for thermal simulation of Autonomous Electric Vehicles (AEVs) is said to be the first such package engineered to address critical, thermal-driven challenges associated with AEV design. “Strategy Analytics expects that the vast majority of self-driving cars will feature electrified powertrains,” said Ian Riches, executive director, Automotive Practice for Strategy Analytics. “The OEMs […]
Simulating electric motors with MotorSolve software
We recently filmed a short video with Chad Ghalamzan from Infolytica, which is now part of Mentor Graphics, a Siemens business. Infolytica develops simulation software called Motorsolve for magnetics as you might find in motors used in electric vehicles. Motorsolve is electric motor design software that allows an engineer to do virtual prototyping of their […]
Power rail analysis using high-definition scopes
Ken Johnson from Teledyne LeCroy recorded a short video with us recently on an eight-channel Teledyne LeCroy scope which was being demoed displaying power signals from a little demo board. The scope was the LeCroy eight-channel, 12-bit, one-gigahertz oscilloscope. In the demo, it displayed five power rails and a current signal and a digital clock […]
HIL systems allow highly dynamic emulation of electric motor, battery components up to 800 V
dSPACE recently complemented its product portfolio for the simulation of electric drives. The hardware-in-the-loop (HIL) systems from dSPACE now allow for the highly dynamic emulation of electric motor and battery components with voltages up to 800 V, which means that all drive components of hybrid and fully electric drives can be represented with a real […]
3-kW 3-phase PFC reference design uses SiC diodes and MOSFETs
Microsemi Corporation announced the availability of its new scalable 30-kilowatt (kW), three-phase Vienna power factor correction (PFC) topology reference design featuring its Silicon Carbide (SiC) diodes and MOSFETS. Developed in collaboration with North Carolina State University (NCSU), the scalable, user-friendly solution is ideally suited for fast electric vehicle (EV) charging and other high power automotive and industrial applications, providing customers with more efficient switching […]
