The algorithms enhance the sensor’s precision, making it possible to accurately measure currents to within 1% at up to 1,300 A and 1.7% at up to 1,500 A, said LEM.

With distance and speed of charging vital in the competitive EV sector high-power integrated traction inverters – which convert DC into AC and capture energy for the vehicle – need to combine ...

Prior knowledge needed: ECEA 5340 Sensors and Sensor Circuit Design. Learning Outcomes Understand how to specify the proper AC or DC motor for a machine design. Integrate the motor to a machine, based ...

This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.

Multiply the 249 Ω times the maximum loop current, 20 mA, to get 4.98 V. Add that to the 12 V needed by the sensor to get approximately 17 V. An 18-V power supply should work, and it does ...

The design is centered around a fully integrated, linear current sensor ACS712 from Allegro. The sensor (in SOIC8 package) consists of a precise, low-offset, linear Hall-effect sensor circuit with a ...

The rest of his design is what appears to be a pretty convoluted power supply section. [Daniel] wanted to power his current probe with a 5V input derived from the USB socket on his oscilloscope.
