Switch Mode Power Supply Operation! Theory plus actual Application Part lll [tagalog]

Описание: Switched-mode power supply (SMPS) is becoming more common and, in most cases, replaces the traditional theoretical linear AC-DC power supply due to reduced power consumption, reduced heat dissipation, and reduced size and weight. Switched-mode power supplies are now available in most PCs, power amplifiers, televisions, DC motor drives, etc., and switched-mode power supplies are becoming more mature, so almost anything that requires a highly efficient power supply is using SMPS.

By definition, an SMPS is a type of power supply that uses semiconductor switching technology instead of the standard linear method to supply the required output voltage. A basic switching converter consists of a power switching phase and a control circuit. The power switching stage circuit performs a power conversion from input voltage Vin to output voltage Vout with output filtering.
