Switch mode power supply, also known as switching power supply, switching converter, is a high-frequency electric energy conversion device, and is a kind of power supply. Its function is to convert a level of voltage into the voltage or current required by the client through different forms of architecture. The input of the switching power supply is mostly AC power (such as mains) or DC power, and the output is mostly equipment that requires DC power, such as a personal computer, and the switching power supply converts voltage and current between the two. The high conversion efficiency of the switching power supply is one of its advantages, and because the switching power supply has a high operating frequency, a small-sized and light-weight transformer can be used, so the switching power supply will be smaller in size and lighter than the linear power supply.
