The MLX91211 Hall current sensor from Melexis comes in two variants providing a choice of accuracy for cost-sensitive e-mobility traction applications, such as two-wheel and three-wheel e-bikes, ...

Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction. When an ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

Members can download this article in PDF format. High-voltage systems including electric vehicles, industrial robots, communications infrastructure equipment, and renewable-energy installations often ...

Designed for EVs and HEVs, these current sensors deliver accurate, isolated measurement for batteries, motors, and safety ...

Two of the top considerations in data center and server power-supply unit (PSU) designs are power density and efficiency. Meeting the strictest efficiency standard—80 Plus Titanium—is now a minimum ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Lem has introduced a pair of mains residual current monitors for electric vehicle charging that have both digital and analogue outputs. One monitors single-phase live and neutral (CDSR 0.07-TP, photo ...

Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...
