For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...

While troubleshooting the power supply of a 1970s Centurion system, [Usagi Electrics] came across a fascinating feature of these units: the ferroresonant, or constant voltage transformer (CVT). The ...

Growing data center power demands are driving server equipment manufacturers to reach higher power-conversion efficiencies in order to reduce the thermal footprint of their systems. The transition ...

The world’s largest flexible DC transformer uses advanced magnetic management and real-time monitoring to move power across 1 ...

Testing is crucial for ensuring the reliability of transformers in power grids. While their electrical function may seem simple, transformers are actually complex machines that require careful design, ...

Solid state transformers (SSTs) represent a transformative shift in power electronics, replacing conventional electromagnetic transformers with semiconductor-based devices that offer enhanced ...

Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

Eight electric power and energy companies have agreed to create a national stockpile of spare transformers and other essential grid equipment that could be deployed to help parts of the high-voltage ...

The financial results of the company have been benefitting from strong global demand for power transformers for the past two years. I’m optimistic that this will last for a few more quarters as the ...
