Systems and methods for reducing inrush current into a component, such as a power converter (e.g., LED driver), which receives alternating current (AC) power from an AC power source (e.g., AC mains). The method may include pre-charging the input capacitance of a component or circuit ...

A negative temperature coefficient (NTC) thermistor (JNR) is made of specially formulated metal oxide ceramic material, which can be used to suppress instantaneous surge current. Compared with the protected circuit, the surge current limiting element has a higher resistance, so it will suppre...
An inrush-limiter circuit gets around the problem by momentarily switching a high power resistor in series with the load to limit the maximum inrush current. Once the surge subsides this series resistor is bypassed so that the load ... W Waetzig - 《Elektor Electronics Worldwide》 被引量:...

These compact devices work well in situations where you don’t have much room on a circuit board. The miniAMP inrush current limiter is an affordable way to protect relays, diodes, and fuses from current surges. You can get them in three sizes: 3mm, 5mm, and 8mm, and they are very ...

Removing the short circuit restores normal operation, allowing Q2 to turn off and Q1 to turn on. Note that, because Q1’s on-resistance acts as a current-sense resistor for this function, the short-circuit trip point may vary depending on ambient temperature and Q1 ’s characteristics. ...
