Circuits that fall under the requirements of Art. 725 are remote-control, signaling, and power-limited circuits that aren’t an integral part of a device or appliance. Article 725 includes circuits for ...

The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

As electronics applications continue to become more compact, powerful, and versatile, the final system demands and complexities of mobile and stationary devices also are becoming increasingly ...

The digital control of switching power supplies is firmly established in everything from EV onboard chargers (OBCs) to power-supply units (PSUs) in AI data centers to renewable-energy systems that ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...

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 ...

One simulates up to 50× faster than the other, and both will give you comparable accuracy. Which engine would you choose for your power supply circuit? Sounds like a trick question, but it isn’t.
