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 :
|Power Conversion||Provides A.C supply when power fails.||Converts A.C to D.C power.|
|Transformers Used||Low-frequency transformers used.||High-frequency transformers used.|
|Backup||UPS have backup capabilities.||SMPS don’t have any kind of backup capability.|
|Power Storage||Power storage equipment is used to store the incoming supply.||No power storage equipment used.|
|Pricing||It is usually costlier than SMPS.||Prices are usually lower than UPS.|
|Placement||Usually outside the cabinet.||Inside the cabinet.|
|Size||Usually, the size is slightly bigger than SMPS.||Usually, Smaller than UPS.|
|Electronic Components||Rectifier, UPS Batteries, Inverter, Static Bypass Switch.||PWM Oscillator, HF rectifier, MOSFET switch.|
|Popular Manufactures||Schneider, Luminous, Su-Kam, Genus Power.||Marc Computers, Thermaltake, Zebronics.|
