Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

VRMs (voltage-regulation modules) that power the latest generations of computer CPUs have historically used multiphase, interleaved buck converters. These VRMs must meet the tight Pentium 4 and Athlon ...

This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...

If you measure a DC voltage, and want to get some idea of how “big” it is over time, it’s pretty easy: just take a number of measurements and take the average. If you’re interested in the average ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.
