To prevent similar situations in the future, Chinese engineers have now developed a 750-megavolt-ampere (MVA) smart DC ...

Following successful final acceptance testing at the Siemens transformer factory in Nuremberg, the world’s first 800-kV transformer for extra-high-voltage DC transmission systems HVDC is ready for ...

This file type includes high resolution graphics and schematics when applicable. Certifying a new power product to relevant safety standards is an essential part of any design and development process.

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

The world’s first transformer, which Siemens developed and manufactured for high-voltage direct-current (HVDC) transmission systems with what is currently the highest transmission voltage of ± 1,100 ...

Seemingly untouched by the telecom downturn's fallout, planar magnetics continues to proliferate in general-purpose dc/dc converter designs for high-frequency, high-efficiency applications. But planar ...

In power supplies, dc-dc converters and many other power electronics circuits, chokes and transformers form an essential part of the filter network that provides low-ripple dc power. In many designs, ...
