Correct Answer - Option 2 :  Switched Mode Power Supply

The correct answer is Switched Mode Power Supply.

  • The full form of SMPS is Switched Mode Power Supply.

  • SMPS or switched-mode power supply 
    • SMPS or switched-mode power supply is an electronic device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. 
    • The circuit consists of a rectifier, voltage regulator transformer, and a filter. 
    • The input supply is turned On and Off by MOSFETs.
  • Fundamentally, different types of circuits work with various kinds of power supplies such as SMPS.

 

  • Difference between Linear Supply and Switch Mode Power Supply
    • The linear power supply and Switch mode power supply, both supplies DC power to electrical circuits.
    • The crucial factor which differentiates linear power supply and SMPS is the working procedure.
    • The Linear power supply converts high voltage AC into the low voltage using a transformer and then converts it into DC voltage.
    • While the switched-mode supply converts AC into DC first then transforms that DC voltage into the desired voltage.
