AC power supply is provided to our homes from grid station, but there are many home appliances that are operated by DC.Justify how they will operate while AC main supply is provided but we have needed DC to operate them.
hi,
Depending upon the power rating of the DC devices you will require mains rated rectifiers.
If the DC devices require a voltage that is not equal to the rms value of the rectified AC mains supply
you will also require mains transformers to match the voltage.
If the DC devices have a DC supply terminal connected as ground onto the DC device, again you will require a transformer for isolation.
Is this clear?
Tell us what the devices are and what are the rated DC voltages/currents, also the voltage of the AC mains supply.

read the history books regarding the battles Westinghouse and Edison waged regarding AC versus DC power transmission. it's interesting reading, and electric chairs are involved!
Yeah, old Thomas A. used to electrocute elephants on stage to demo that AC was more dangerous than (his) DC. People do wierd sh1t when they are chasing the big bucks.
