Cleaner output for clean energy

For renawables delivering direct current, the output current should be as 'clean' as possible since it has to be converted to AC. Siemens has just introduced an inverter topology taking care of this challenge.

Cleaning up Britain

 With rising energy prices and stringent requirements for producing a higher proportion of energy from renewable sources in the near future, long-distance electricity cables are increasingly thought of as a viable option for providing electricity. Now, even the British government is looking into clean energy - far away from home.

A battery for continuity

While renewable energy obviously is a good idea, sources like wind and sunshine have the downside of not flowing constantly 24/7. Furthermore, the time of day where, for example, the sun is shining, might not be the period with the highest demand - at least not in Europe, where aircondition isn't a matter of course as it is in other parts of the world. So, one of the major obstacles for the energy changeover is the problem of storage.

Intersolar 2012: Efficient inverting

Silicon carbide technology has secured its place in power electronics in a hurry. The advantages are obvious, even though the material is rather difficult to handle. At this year's Intersolar trade fair, SiC solar inverters hit the market on a broad scale.
