    Know all about Switch Mode Power Supply

      Switch Mode Power Supply

      A switch mode power supply (SMPS) is basically an electronic power supply which efficiently converts electrical power. It transforms power coming from the main source and gives it to the load like transformer. It converts current and voltage characteristics. The transistor in this supply switches between low dissipation, full off and full on states and […]
