10 Applications of SMPS in Power Supply With Examples, Types, and Block Diagram

In today's post, we will learn 10 applications of SMPS in Power Supply with examples, different types, explanations, advantages, disadvantages, and block diagrams.
The Full Form of SMPS is Switch Mode Power Supply.

The SMPS {Switch Mode Power Supply} is used to provide electric current to the parts of the device.

The primary function of SMPS is to convert A.C. voltages to D.C. voltages. When voltages need to be converted from AC. to DC.

SMPS is used prominently in such devices.

Let's get started

What is SMPS {Switch Mode Power Supply} With Block Diagram and Explanation?

The switch-mode power supply works with 220 to 240 current supplies.

We receive an A.C. power supply directly, and this power supply cannot be used in computer systems directly as the computer needs a D.C. power supply to work and function properly.

If we present A.C.’s power supply directly to the computer system, the huge power supply will damage internal parts like the motherboard, ram, components, hard disk, etc.

Therefore, SMPS converts the A.C. power supply to D.C. for the computer system to function and work properly.

The computer motherboard is responsible for providing further electric voltages to other parts and components of the computer system.

Therefore, the SMPS is considered the essential part or device of the system.

Applications of SMPS in Power Supply With Examples

  1. They are primarily used in personal computers, power stations, ovens, fridges, etc.
  2. They are used in batteries.
  3. They are used in manufacturing units and factories to provide adjustable power and voltages
  4. They are also used in security systems, railway systems, servers, power stations, railways, airports, etc.
  5. They are used in modern Smart Phones.
  6. The SMPS is also used in the automobile sector.
  7. They are used in electric equipment.
  8. With the help of a frequency changer, A.C. voltages are converted to A.C., and D.C. voltages are converted to D.C.
  9. The SMPS is used to stable the electric current and help to balance the overload current.
  10. The SMPS is also used to balance unregulated DV input voltages.
  11. They have Electromagnetic compatibility.
