Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...

The methods of protecting electronics from circuitry failures and managing inrush current at power on has evolved significantly from a simple fuse and maybe a P-channel FET to much more sophisticated ...

Inverters are electrical systems that provide variable voltage (ac output) when connected to a dc-input source. Inverters are available in two varieties: three phase and single phase. These inverters ...

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 ...

MALVERN, Pa., Oct. 30, 2024 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of inrush current limiting positive temperature coefficient (PTC) thermistors.

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system. These inrush currents can cause sags ...

MALVERN, Pa., Oct. 22, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (VSH) today introduced a new series of insulated, surface-mount inrush current limiting positive temperature coefficient ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

The portfolio of ac inrush current limiters from Camtec Power Supplies has been expanded to include the new ESB001 series. This series is currently the world’s smallest for its performance class, and ...

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 ...
