All questions and answers are based on the 2017 NEC. Q. Per the NEC, overcurrent protection devices must be placed at what location in branch-circuit or feeder conductors? A. Except as permitted by ...

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

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 ...

For the PDF version of this article, click here. Protecting power transistors against overcurrent failure has always been a challenging issue in power circuit design. In order to protect against even ...

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 ...

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 ...
