The current limiting circuit, though, is where things get interesting. Rather than use an op-amp, [DiodeGoneWild] chose a simple discrete transistor current-sense circuit.

From there, zero-crossing detection is added to limit inrush surge currents, and the final design uses the venerable 555 timer to build a switching power supply.

Smallest (1.075 in2), lightest weight (16g) hermetic inrush current limiter available High 99% efficiency Hermetic package ensures full performance over -55 degrees C to +125 degrees C military ...

For example, if the circuit is designed to current limit at I CL = 500 mA, and if the supply voltage, VS, could reach a maximum of 15 V, a short circuit across the load could dissipate almost 7.5 ...

With a power capacity of 200W, the DVCL inrush current limiter controls inrush current drawn by dc/dc converters, EMI filters, and discrete capacitors during startup. Groomed for avionics and ...

Fault current limiters (FCLs) serve as essential protective devices within modern power systems, mitigating the potentially damaging effects of fault currents. By dynamically increasing their ...

Zenergy Power has announced the receipt of the first commercial order for a superconductor Fault Current Limiter. Placed by UK-based Applied Superconductor Limited, the order is for the purchase of a ...

ETI Chief Executive Dr David Clarke said: “Although we hear a lot about the importance of renewable energy sources to the UK’s future energy mix, the infrastructure that provides power and heat to ...
