Racking in or out a power circuit breaker is simple, right? Although this task sounds pretty straightforward in theory, that’s not always the case. In fact, during years of field work related to ...

Several types of devices are employed in electronic systems to protect against voltage transients, power surges, and excessive voltage or current. Varistors is one of those devices that protect ...

Silicon MOSFET power transistors have been a mainstay of power-supply design for years. And while they’re still widely used, gallium-nitride (GaN) transistors are gradually replacing MOSFETs in some ...

The aim: Create a 3.3V source from a –5V supply. You can obtain a precise, positive-output voltage from a negative-voltage supply with a boost converter and a linear regulator. The input and output ...

This week the world’s first and only digital circuit breaker was certified for commercial use. The technology, invented by Atom Power, has been listed by Underwriters Laboratories (UL), the global ...

Electrical overcurrents can not only damage systems, but also cause costly downtime. Fuses are said to be a great way to protect a battery energy storage system (BESS) simply and cost-effectively. In ...

In the electrical profession, questions still arise about what type of circuit breaker to use with surge protectors. Don't make this task more difficult than it has to be. Choosing the right device is ...
