KNOWLEDGE BASE --- AC-DC Switching Power Supply
AC is the alternating current, which generally refers to the voltage or current whose magnitude and direction change periodically, whose most basic form is sine-wave current.
DC is a direct current, which refers to a current whose direction and time do not change periodically, but the magnitude of the current may not constant, also known as a constant current.
AC-DC switching power supply is an Alternating Current (AC) to Direct Current (DC) switching power supply, most of which convert the 110V/220V Alternating Current of the mains into low-voltage Direct Current for supplying power tools, office equipment, home appliance and industrial control equipment, such as the power supply part of TV sets and monitors, etc.
