What are the driving forces behind expansion of LVDC beyond Data Center Applications?

What are the driving forces behind expansion of LVDC beyond Data Center Applications?

The ability to directly link between photovoltaics or energy storage mechanisms and direct current (DC) rated utilization equipment is an attractive option to avoid the potential energy losses and heat generation associated with power conversion from DC-to-AC-to-DC.  Many pieces of utilization equipment, particularly IT, home electronics and appliances, and office equipment are actually operated by DC supplied from individual power supplies that convert the AC current from the utility or building Read more [...]

LVDC – Wave of the future or Technogimic?

Lately, a return to using low voltage DC power, at least in some applications, had gotten a lot of attention.  There was a US workshop sponsored by NEMA, UL and NFPA that drew over 140 participants.  A workshop was recently held in Europe that had over 70 attendees.  Demonstration installations for data centers and community level distribution have been constructed and tested.  A consortium, EMerge Alliance, has developed a standard and applications for using LVDC for office lighting Read more [...]

LVDC and Harmonic Currents

NEMA, UL and NFPA sponsored a very successful workshop in Crystal City, VA during April on the topic of Low-Voltage Direct Current.  There were 17 presenters and over 140 attendees at this state-of-the-industry event.  LVDC is of interest because establishing a direct connection between distributed power generators (especially photovoltaics) plus energy storage devices (mostly batteries) and the many electronic products that operate on LVDC allows elminiation of Read more [...]
