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 ...

Inside nearly every electronic device is a simple coil of wire doing a powerful job—it’s called an inductor. Though small and ...

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 ...

Electricity powers everything from your phone to your refrigerator—but have you ever wondered how it’s controlled inside a ...

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 ...
