DC Power

We live in the world that runs on electricity: alternating current (AC) and direct current (DC). The flow of electrons shapes our daily lives, everything we produce and everything we do. To find out more about AC and DC and their place in the past as well as in the modern world watch this video.

Just out of curiosity, did they say anything about 15 volts? I think the number is 380 volts which is more efficient than 240 or 480 AC when you factor in renewable energy like PV coming in at 380 volts DC and direct-coupling right to the 380 bus. No inversion from DC to AC and back to DC required.

Complete mis-information. I would like ABB to explain why they cant make simple efficient power supplies. Just imagine all the copper that would be needed to distribute 15v DC at thousands of amps around an IT center? That car charging example was just ridiculous. Also on DC railways one has to feed 750v DC at up to 5000 amperes. The only way to do that is have substations every couple of miles fed with high voltage AC.

Nice Integration :)
