A switched-mode power supply ( SMPS) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

Switching power supplies have taken over linear AC/DC power supplies because they are smaller, more efficient, and are capable of handling high power. Picture 1 illustrates the general transformation from alternating current (AC) to direct current (DC) in a switching power supply.

According to the usage and design,there are OEM power transformer,Wall Power Adapter,Desktop Power Adapter,Control Transformer,AC To DC Power Supply,Linear Power Supply etc products.
