In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

What's driving the need for protection devices and the challenges of implementing them. Traditional types of protection devices. Different approaches to protection, including surge stoppers. The ...

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp. I put a hose ...

Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

Find a downloadable version of this story in pdf format at the end of the story. Although features and functionality attract the most attention for new electronic products, whether consumer, ...

Adding components to provide circuit protection against internal and external mishaps is one of those thankless design jobs, similar to buying insurance. When it’s not needed, it seems like an added ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...

Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...
