Advantages and disadvantages of SMPS

The disadvantages of linear power supplies (LPS), such as lower efficiency, transformers used are heavier and large, more power is wasted in the form of heat, dissipation is more etc. Overcome by implication of SMPS. So now let us talk about the advantages and disadvantages of SMPS to know more details about SMPS. first, let us check it out full form of SMPS

Advantages of SMPS :
  • The efficiency is high as compare to LPS, more than 80 to 90%
  • The device is used in SMPS is compact and very small in size
  • The manufacturing cost is reduced
  • Provide isolation between multiple output
  • Low power wastage
  • Less heat generation
  • High power density
  • Flexible technology
  • Lower weight
  • Providing the required number of voltage
  • Strong anti-interference
  • Reduced the harmonic feedback into the supply mains
  • Wide ac input voltage
Disadvantages of SMPS :
  • Greater circuit complexity
  • Expert design are required
  • High frequency electrical noise
  • It can be used step down regulator 
  • The noise to present due to high-frequency switching
  • It produces electromagnetic interference
  • Harmonic distortion
  • Only one output voltage
  • Expensive compared to LPS
The main advantages of SMPS over conventional linear power supply are as under :
  • SMPS is less sensitive to input voltage variations
  • For the same power rating, SMPS is of smaller size, lighter in weight, and possesses higher efficiency because of its high-frequency operation.
The disadvantages of SMPS are as under :
  • SMPS has higher output ripple and its regulation in worse
  • SMPS is a source of both electromagnetic and radio interference due to the high-frequency switching
  • Control of radio frequency noise requires the use of filters on both input and output of SMPS
