SMPS Power Supply Components

SMPS power supplies are used in a wide variety of electronic devices, including computers, smartphones, TVs, and other appliances. They are more efficient and compact than traditional linear power supplies.

Here is a summary of the functions of each component in a switched-mode power supply:

  • Rectifier: Converts AC input voltage to DC voltage.
  • Filter: Smooths out the DC output voltage from the rectifier.
  • Inverter: Converts the DC output voltage from the filter to a high-frequency AC voltage.
  • Transformer: Steps up or down the voltage of the high-frequency AC voltage from the inverter.
  • Rectifier: Converts the high-frequency AC voltage from the transformer back to DC voltage.
  • Filter: Smooths out the DC output voltage from the rectifier.
  • Controller: Controls the operation of the inverter and other components in the SMPS.
  • Snubber circuit: Helps to reduce EMI from the SMPS.
  • Clamp circuit: Helps to protect the components in the SMPS from overvoltage.
  • Fan: Cools the components in the SMPS.
  • Heat sink: Dissipates heat from the components in the SMPS.
