DC micro grid is the way to go especially for the rural communities in developing countries as it allows for many options of renewable energy integration. So your DC transformer will be a great plus.

SpeciaIly, the " Arizona & Sahara desert" like areas.....

Dear Newt Ball,

I strongly believe DC Microgrid is the way forward...considering the fact that (i) almost all appliances have an internal AC-DC conversion stage, (ii) power quality issues in AC systems and (iii) probably the availability or PV in DC form makes it much easier atleast to think in terms of DC.

Eagerly waiting to see DC used predominantly ! Cheers !

Prabhakar,

My DC Transformer invention should be very useful in DC Microgrids.  Alink to a description:  https://1drv.ms/b/s!ApYl96h2rQbBgat9EWU3v69QBwJiUg
