A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Puzzled by choosing circuit protection devices? Follow these guidelines and your electrical system will fall into place. Is it sufficient to select protective devices based entirely on their ability ...

Traditional synchronous boost converters offer little to no protection against short-circuit events at the output. Due to the boost converter’s topology, when the output is shorted to ground, a direct ...

Automotive applications need “smarter” drivers for their switches, which handle loads ranging from a fraction of an ampere to several amperes. Not only are these smart chips costly, but many times, ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

Siemens SENTRON air circuit breakers are enhancing low-voltage protection and switching with fault protection with digital ...

Have you ever wondered why a car’s city fuel economy is always lower than its highway fuel economy? Most cars spend a lot of time stopping or traveling at low speeds, especially in a city. Start-stop ...

A German research team has developed a semiconductor-based protection concept tailored to renewable energy systems that forces a permanent short circuit in less than 1 millisecond in the event of a ...

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

Self-protecting starters (SPSs) were first introduced to the U.S. in 1987. However, SPSs have been used internationally for several years. Recently, several manufacturers and private labelers have ...
