1. Switched Mode Power Supply (SMPS) :
It is used to change from a specific DC voltage to another DC voltage level usually it reduces the supply voltage to a lower level so that it can be used by components requiring lower voltage.

2. Uninterruptible Power Supply (UPS) :
It is used to supply power to devices for a fixed amount of time without stopping even when there are is no incoming power supply.


Difference between S.M.P.S and U.P.S :

ParameterUPSSMPS
Power ConversionProvides A.C supply when power fails.Converts A.C to D.C power.
Transformers UsedLow-frequency transformers used.High-frequency transformers used.
BackupUPS have backup capabilities.SMPS don’t have any kind of backup capability.
Power StoragePower storage equipment is used to store the incoming supply.No power storage equipment used.
PricingIt is usually costlier than SMPS.Prices are usually lower than UPS.
PlacementUsually outside the cabinet.Inside the cabinet.
SizeUsually, the size is slightly bigger than SMPS.Usually, Smaller than UPS.
Electronic ComponentsRectifier, UPS Batteries, Inverter, Static Bypass Switch.PWM Oscillator, HF rectifier, MOSFET switch.
Popular ManufacturesSchneider, Luminous, Su-Kam, Genus Power.Marc Computers, Thermaltake, Zebronics.
