Anybody interested in building their own robot, sending spacecraft to the moon, or launching inter-continental ballistic missiles should have at least some basic filter options in their toolkit, ...

Where measurements involve alternating current only, passive current transformers with suitable core materials can be used. However, currents in pulsed converters in particular, also contain ...

For the PDF version of this article, click here. Traditional motor-phase-current sensing methods depend on sensors with signal bandwidths of 100 kHz or greater. Problematically, such bandwidths allow ...

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 ...

Analog filter design remains a cornerstone of modern signal processing, instrumental in a vast array of applications spanning telecommunications, instrumentation, and biomedical engineering. Recent ...

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 ...
