Understanding on How Switch Mode Power Supply Works

Some of us like technician want to learn more about the Switch Mode Power Supply commonly called SMPS. This is a special type of power that uses a chopper transformer instead of an ordinary metal core transformer. We have to learn how this type of power supply works for us to have knowledge on how to repair this switch mode power supply if we will encounters problem related to power supply.
According to wikipedia:

A switched-mode power supply (switching-mode power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a source, like mains power, to a load, such as a personal computer, while converting voltage and current characteristics. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage.A switched-mode power supply (switching-mode power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

This type of power supply is commonly used on television sets and DVD players and now some component sytem like the Sony already uses this type of power supply to their electronics products. To learn more about Switch Mode Power Supply, visit: smpstroubleshooting.com.
