Introduction
Switch Mode Power SupplyIt is an electronic power supply that incorporates a switching device in order to be highly efficient in the conversion of electrical power
A: input EMI filteringB: input filter capacitors;C: transformer;D: output filter coil;E: output filter capacitors.
Benefits of SPS(switch power supply)
High efficiency and less heat generation(Linear mode power supply efficient 40~50%)
(Switch mode power supply efficient 70~95%)
Tighter regulation
Smaller size
