Do you know the facts about circuit protection, or have you just been relying on what you hear around the shop? As an electrical contractor, system designer, plant electrician, or electrical inspector ...

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 ...

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 ...

Note: This article is based on the 2011 NEC. Article 430 provides the requirements for electric motors while Art. 440 offers amended and additional requirements for hermetic motors, such as those used ...

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 ...

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 ...

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

For modern distribution protection, Negative Phase Sequence (NPS) Protection is often relegated in favor of common elements such as Overcurrent (OC) or Earth Fault (EF), but NPS is an incredibly ...

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched a CMOS dual comparator, "TC75W71FU." It features a high-speed response and a full input/output range (Rail to Rail), suiting ...
