Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...

The circuit is designed for power supply protection by limiting the amount of maximum output current to prevent any further damage to take place inside the power supply as well as the external circuit ...

Siemens develops superconducting fault current limiters for limiting short-circuit currents in the grid. Superconductors show zero resistance below the critical temperature and below the critical ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...

At a power-on cycle, inrush current, if not limited, can peak to tens of even hundreds of amps when capacitive load is present, thereby increasing the probability of failure and decreasing usable ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

Brushless dc motors have the advantages of high reliability and smaller size, but the absence of brushes can pose challenges. One challenge is the requirement for electronic commutation and control, ...
