SMPS (Switched-Mode Power Supply)<\/strong>\u00a0is an electronic power supply that efficiently converts electrical power using switching regulators. Unlike traditional linear power supplies, SMPS rapidly switches transistors on and off to regulate voltage, resulting in\u00a0higher efficiency, compact size, and less heat generation<\/strong>.<\/p>\n\n\n\n

Key Features of SMPS:<\/strong><\/p>\n\n\n\n

    \n
  1. High Efficiency<\/strong>\u00a0(70-90%) \u2013 Wastes less energy as heat compared to linear power supplies.<\/li>\n\n\n\n
  2. Compact & Lightweight<\/strong>\u00a0\u2013 Uses high-frequency switching, reducing the need for large transformers.<\/li>\n\n\n\n
  3. Wide Input Voltage Range<\/strong>\u00a0\u2013 Can work with varying AC inputs (e.g., 110V\u2013240V).<\/li>\n\n\n\n
  4. Multiple Output Voltages<\/strong>\u00a0\u2013 Provides different DC outputs (e.g., +12V, +5V, -12V).<\/li>\n<\/ol>\n\n\n\n

    How SMPS Works:<\/strong><\/p>\n\n\n\n

      \n
    1. Rectification<\/strong>\u00a0\u2013 Converts AC input to DC.<\/li>\n\n\n\n
    2. Switching (Chopping)<\/strong>\u00a0\u2013 High-frequency switching (kHz-MHz) using MOSFETs\/BJTs.<\/li>\n\n\n\n
    3. Transformation<\/strong>\u00a0\u2013 Steps voltage up\/down via a high-frequency transformer.<\/li>\n\n\n\n
    4. Rectification & Filtering<\/strong>\u00a0\u2013 Converts back to smooth DC output.<\/li>\n\n\n\n
    5. Feedback Control<\/strong>\u00a0\u2013 Adjusts switching to maintain stable voltage.<\/li>\n<\/ol>\n\n\n\n

      Types of SMPS:<\/strong><\/p>\n\n\n\n

      Type<\/strong><\/td>Description<\/strong><\/td><\/tr><\/thead>
      AC-DC SMPS<\/strong><\/td>Converts AC mains to DC (common in computers).<\/td><\/tr>
      DC-DC SMPS<\/strong><\/td>Converts one DC voltage level to another (used in laptops, cars).<\/td><\/tr>
      Flyback Converter<\/strong><\/td>Used for low-power outputs.<\/td><\/tr>
      Forward Converter<\/strong><\/td>Used for medium- to high-power outputs.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
