Question

The disadvantage of smps over conventional linear power supply is​

Answer 1

Answer:

The main difference between the linear power supply and SMPS is that linear power supplyconverts the high voltage of AC into low voltage AC first then the rectification procedure takes place. On the contrary, theSMPS converts the AC signal into DC signal first then the stepping down of voltage signal takes place.

Answer 2

The disadvantages of SMPS are as under : SMPS has higher output ripple and its regulation in worse. SMPS is a source of both electromagnetic and radio interference due to high-frequency switching. Control of radio frequency noise requires the use of filters on both input and output of SMPS.
