Efacec Power Transformers Inc. has successfully shipped the largest shell transformer made in the U.S. in more than 20 years. The electrical transformer has the unique feature that it can be delivered ...

The use of power electronics is increasing in the industry for both low-scale applications like chargers for batteries and LED drivers and high-scale applications like photovoltaic (PV) systems and ...

Electrica signature analysis (ESA) uses the magnetic field in the air gap of an electrical machine to evaluate power quality conditions. Dry and oil transofrmer types are subject to problems ...

Planar transformers and inductors for high-frequency converters differ radically from conventional magnetics in that they do not use magnet wire. Instead, windings are copper-foil lead frames or flat ...

Topology that is result of the project provides a possibility of achieving maximum physically attainable level of energy that can be received from a ferromagnetic transformer. Specified inverter is ...

POSTECH and a group of researchers developed a technology that dramatically improves the performance of plasmonic photocatalysts using 'core@shell' nanocrystals with atomically conformal metal ...
