The number of consumer electronics has increased considerably specially in residential buildings, I would like to know What is the percentage of the DC electric loads? or any research papers regarding this topic?
Wild guess 80 to 90% referring to load number. Not to actual energy consumption.
Waterboiler, microwave or normal oven wash machine and toaster (and stove) are not on dc probably
Most DC loading is supplied by power supply connected to AC source, hence loading could not be considered as DC....
Yeah in most systems there is a SMPS (Switched mode power supply) but there are LED lamps with just a single diode, which is active in one phase halve. Hence this is DC. But most equipment in the home is DC powered, an adapter (SMPS) is needed to power it. On a wider view a complete new building in NL is a DC building... DC powered, but the are using a huge SMPS to provide the DC, is this a DC load or an AC load depends on your view.
Dear Edwin, thank you very much for answering my question, the papers you attached are valuable and I read them.

Dear Cees, thank you very much for your answer, yes I think the number is roughly in this range.

Dear Bhupendra, thank you very much for contributing to the answers, what I meant the loads that are internally DC powered, for example consumer electronics need always adapter in order to be powered from the mains but they are DC loads.

Dear Ashraf,
Now a days we are utilizing the dc loads by consumer electronics especially for charging devices. it might be around 90 -95% only for the above.
Best regards
