How much will be the power loss in SMPS of a brushless DC motor based ceiling fan?
Input is 230V AC,
Output is 24VDC,
Fan consumed 28W at highest speed of 350rpm.

YOU NEED TO PROVIDE INPUT CONSUMPTION POWER IN WATT FIRST BEFORE ABLE TO FIGURE IT OUT.

Switch Mode Power Supplies run at typically 85 - 90% efficiency.
using the 90% number, 28 W / 0.9 = 31 watts input, with a los of 3 watts.
Could be a loss of 4 watts if the efficiency is a bit lower.
