SMPS (switched-mode power supply)

A switched-mode power supply (SMPS) is an electronic device that efficiently converts electrical power from one form to another, such as from AC (your wall outlet) to DC (used by devices like computers). It works by rapidly switching on and off, controlling energy flow, and using components like transformers and capacitors to regulate voltage and current. This process makes the power supply lightweight, compact, and energy-efficient compared to traditional methods. SMPS is common in many electronics because it provides reliable power in a small size while minimizing energy waste.
