ORNL researchers are designing and increasing the capacity of a new type of semiconductor-based circuit breaker, which can ...

“ORNL researchers designed solutions and tested them in a series of breakers operating up to an 1,800-volt testing capacity,” added the press release. They are now working toward systems that can ...

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) say they have developed medium-voltage ...

The rapid expansion of high voltage direct current (HVDC) grids, driven by the massive integration of renewable energy sources, has underscored the critical role of DC circuit breakers (DCCBs) and ...

Edison was right; direct current is better than alternating current. Tesla and Westinghouse won the current wars, because it was easy to transform into different voltages without electronics, and ...
