LEM has announced three-phase current sensors that fit silicon carbide power modules typically used in 800V vehicle traction inverters. “Developers of automotive traction inverters are increasingly ...

As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...

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 ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

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 ...

NxtPhase T&D Corporation has announced the NXCT-F3 flexible optical current sensor. The latest addition to the NxtPhase range of optical CTs, the NXCT-F3’s flexible, fiber optic head wraps around high ...

An interdisciplinary team of scientists has demonstrated optical and electronic evidence of semiconductor-to-metallic phase transition when exposed to airborne chemical vapors, and how the behavior ...

A while back, one of our coworkers was working on some of the challenges that are inherent in designing smartwatches, fitness wearables, and the like. One of the main challenges is how to get better ...

Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...
