All questions and answers are based on the 2017 NEC. Underlined text indicates a Code change. Q. What does the Code require for overcurrent protection of flexible cords, flexible cables, and fixture ...

With the rise of vehicle electrification, the number of digital power control systems and electric motors in automobiles is expanding rapidly. Correspondingly, electrical systems must be as efficient ...

This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...

One of the most common reasons to measure current in today’s automotive systems is to detect fault conditions and respond to them quickly. I touched on this topic previously in Signal Chain Basics ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

This 'back-to-the-basics' video that explains how non-directional overcurrent works. It shows the difference between a fuse and an overcurrent protections scheme with current transformer, relay and ...

Solid-state overcurrent-protection ICs such as USB switches and card-slot power switches offer a simple and robust protection for pins at risk of overloads and short circuits. Such switches, however, ...

The new product offers a faster propagation delay than the current TC75W56FU, with a maximum of 45ns for low-to-high ...
