Question

State the full form of SMPS:
1. Simple Mode Power Supply
2.  Switched Mode Power Supply
3. Simple Multiple Power Supply
4. Switched Multiple Power Supply
5. None of these

Answer 1

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.
