SMPS D.C. Power Supply

What is SMPS D.C. Power Supply?

A Switched-Mode Power Supply (SMPS) DC Power Supply is an advanced electronic power conversion system that efficiently regulates and delivers DC (Direct Current) power from an AC (Alternating Current) or DC input source. Unlike traditional linear power supplies, SMPS operates using high-frequency switching technology, making it more compact, energy-efficient, and reliable.

 

How SMPS DC Power Supply Works

  • SMPS converts electrical power through a series of switching and regulation processes:

    1. Rectification & Filtering – Converts AC input into DC.
    2. High-Frequency Switching – Uses a transistor-based switching circuit to rapidly convert and regulate voltage.
    3. Voltage Conversion – Steps up or steps down the voltage as required.
    4. Rectification & Output Filtering – Provides smooth, stable DC output for powering devices.
