Electricity: The 'return' of the DC (direct Current) – LVDC Miscellaneous
A 'war of voltages' is expected to burst out in the 'DC world'...
It might be even more 'everlasting' than the previous 'war of currents', and there is still an unpredictable result...
And, the more, it is already silently unfolding, thus not yet is it 'loudly' declared. And it might last as long,.. till the 'Ascension' process.
For now, the 'war of voltages' concerning LVDC distribution, (and above the 'established' values of 12, 24, 48V ELVDC), may unfold (and 'rage') including LVDC voltages as might be 120, 125, 220, 240, 300, 350, 380, 400, and even 550V DC...
So, outside of this war can be considered the DC (extra low) voltages as are 12V, 24V, 48V DC. And,... in this range, as the case may be, have we to design our stand-alone DC (solar power or other kind of 'free energy') nano-grids.
However, in this 'war of DC voltages' there are expected some 'happy ends' to occur, on some 'fronts' of interests...
Why seem this particular 'war' a non-destructive one, is that all the 'combatants' have the same interest: promoting a 'DC world' against the currently 'all seeing' AC of 50/60Hz distribution.
This 'war of DC voltages' may lead in fact to a win-win solution on the 'DC side' of combatants,... and hopely to a 'win-lose' in the favor of DC against the highly disgusting AC of 50/60Hz.
And, as expected, a 'proxy' of this undeclared 'war of DC voltages' is also unfolding in the IEC, in order to set up the needed LVDC standards, finally with a preferable 'win-win' resolution in the form of a broad range of standardized LVDC voltages.
