Hi Swati,

SMPS means Switched mode power supply and is an electronic device which converts or switches required dc voltage to the appliances. Mainly this accepts AC voltage and convert into DC voltage and gives proper supply to the appliances

In simple words you can say this is a power converter like any other transformer.

Hope helped you

SMPS, Switched Mode Power Supply is a power supply unit mostly used in desktop computers, television and other electronic devices, transistors and IC's are used to make this device, unlike the past power supply units were used heavy transformers and bigger and bigger condenser, which causes damages of the unit due to heat. The SMPS is used in computer to reduced the heat.

Hello swathi,

SMPS means Switch Mode Power Supply.As the name suggests it is used to switch the Alternating Current(AC) voltage into Direct current (DC) voltage which is required for our computer systems to work.It is placed inside the C.P.U of our computer and from this SMPS connections are given to the CD/DVD drive,Hard disk and to all parts of the computer.

Function of SMPS is similar to the transformers that are seen on the streets near our houses.These transformers also convert AC into DC voltage and supply it to our houses.But we cannot place a transformer in our computers as space occupied is too large.So,SMPS are introduced in the place of transformers.It is very efficient and very low heat is produced by this.

in general it is highly reliable and can guarantee you an efficient work up to 5 years.But if there is any fluctuation in your power line that will directly effect your SMPS and it may be damaged.

Hope you got required information about SMPS you needed.

Best Regards,
Krish.

The other variant is LMPS. (linear mode power supply)

Hello Swati

A switched-mode power supply, switch-mode power supply, or SMPS, is an electronic power supply unit (PSU) that incorporates a switching regulator — an internal control circuit that switches power transistors (such as MOSFETs) rapidly on and off in order to stabilize the output voltage or current. Switching regulators are used as replacements for the linear regulators when higher efficiency, smaller size or lighter weight are required. They are, however, more complicated and their switching currents can cause noise problems if not carefully suppressed. As with any offline electronic systems employing peak-hold AC-DC conversion, simple SMPS designs may have a poor power factor.

It is nothing but power supply box in CPU,SMPS means switch-mode power supply.It converts AC voltage into DC.
