[Mike Worth] wanted the option to run his Microwave Oven Transformer welding rig at less that full power. After being inspired by some of the other MOT hacks we’ve featured he figured there must be a ...

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 ...

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 ...

GridON has announced a new family of inexpensive fault current limiters with smaller footprint for mid-to-high-voltage applications. GridON’s established technology has been further enhanced to offer ...

A new theory could help build future superconducting alternating-current fault-current limiters for electricity transmission and distribution systems. The work identifies design strategies that can ...

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 ...

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 ...

CAMTEC is launching the second-generation AC current limiters. Due to their cooling system, they can be installed wall-by-wall with the other components. The company claims the new CAMTEC ESB001 ...

With the rapid development of power electronic devices and the urgent need for ship electrification, the medium voltage direct current (MVDC) integrated power system is regarded as the development ...

A new method of circuit protection allows designers greater flexibility and increased reliability while reducing the time to market. The long-accepted assumption that hundreds of amperes and thousands ...

Eriez, the majority shareholder of United Kingdom-based FaultCurrent Ltd. (FaultCurrent), recently completed a round of independent tests of its next-generation Fault Current Limiter (pmFCL), which ...
