When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

A bi-directional current source for a grounded load will always have some complication in its construction. The improved Howland Current Pump as shown in Figure 1 is the most frequent choice for this ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

The course is focused on current-mode control techniques, which are very frequently applied in practical realizations of switched-mode. Upon completion of the course, you will be able to understand, ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

This file type includes high resolution graphics and schematics when applicable. A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the ...
