Rogowski coils (see Sidebar and References 1 and 2 at end) perform passive current measurement and are used in test and measurement devices and power-monitoring activities. Calibration is required to ...

The circuit was designed to implement special category of preamplifiers where the output from a moving coil head is amplified before passing to the input of the preamplifier. The circuit was designed ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Buck-boost converters produce a regulated output voltage either less than or greater than the input voltage. When the input voltage is higher than the output, the converter acts as a buck. When the ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...
