Phase correction in mobile charger?

Hi,
I am trying to build a power supply for a 1 kW DC motor. I read somewhere that, as a requirement, a device must always draw a sinusoidal current from the household supply, so it is required to build a phase correction circuit which always draws a sinusoidal current. I am wondering whether all the electrical appliances we use such as a mobile charger, washing machine, TV, etc., really draw a sinusoidal current from the household supply. What about the SMPS we get in the market, does it also draw sinusoidal current? Please help.
Thanks,
aforak
 
If the SMPS is plugged into the house AC current then yes. If connected to a battery then no. As far as household devices anything plugged into the AC house supply must be able to accept the AC current. This is required to prevent the magic smoke from being released.
