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 ...

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 ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

The A_S-1WR and B_LS-1WR series of 1-W SIP dc/dc converters feature continuous short circuit protection and are enclosed in a 0.77 x 0.37 x 0.24-in. package. They feature a continuous output short ...

For the PDF version of this article, including diagrams and/or equations, click here. In any off-line flyback converter design, it is possible that the output ...

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.

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 ...

When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 VDC supply and keeping load circuits that aren’t impacted by the failure ...

Surge protection for an electrical panel controls how transient voltages enter and spread through branch circuits inside the ...

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.
