SMPS is a AC to DC converter so its use as a dc supply.

Answer / shinyvikram ganji

smps is a kind of dc-dc converter.
smps are very sensitive and compact and they are free of
ripple content in there output.thats why there are used in
most ofthe electronics devices today.

smps also works on ac supply
ac-supply--->rectifier---->dc-dc converter--->filter---->o/p

Answer / nisha

smps stands for switched mode ( switching mode) power
supply.This can be used for both ac-dc conversion and dc-dc
conversion...so there is no doubt it can work in dc supply

Answer / sunil parmar,nirma uni.

yes,SMPS can work in a DC supply ----
simple conv. function with AC supply in SMPS

AC--step down to AC---rectified to DC---further step down
to required DC---filtered---o/p

now conversion procedure with DC supply in SMPS

DC---with the help of chopper converted to required DC---
filtered---o/p

Answer / vikas v

Yes ,If it doesnt have input step down tfr.

Answer / raman

YES,PREVIOUSLY IT IS GETTING AC TO DC.
SMPS STANDS FOR SWITCH MODE POWER SUPLY.
IT IS NOT NORMAL POWER SUPPLY, IN NORMAL POWER SUPPLY WE
CANNOT ABLE TO GET DIFFERENT VOLTAGE AT A TIME. BUT IT IS
POSSIBLE IN SMPS WE CAN GET +5V,-5V,12V,-12V,0V ETC.

Answer / mrt

a smps is a switched mode power supply.it is a switch
between one supply to other.it can operate in AC as well as
DC

Answer / a.mitra

yes,smps works in dc supply.we know that ac means high &
low supply,but smps needs stable supply oparate,so smps
