[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 ...

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 ...

Using a current limiter in boost converters for circuit protection. An easy-to-implement design idea to achieve the desired current limiting. 1. A current limiter is added to a power bank that has an ...

The Motor control ICs of the TDA514x family have been provided with an on-chip current limiter circuit. The current limit value, however, can not be set externally. Therefore the need came-up for an ...

The MAX14691–MAX14693 adjustable overvoltage, undervoltage, and overcurrent protection devices guard systems against overcurrent faults in addition to positive overvoltage and reverse-voltage faults.

Fig 1. Placing this two-terminal circuit between a GFCI line-load terminal and ground creates an adjustable line-voltage limiter. Fig 2. With the trip point set at 133 V rms, the circuit draws less ...

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 ...
