What is a switching power supply?

Switching power supply is also called switching power supply and switching converter.

It is a high-frequency electric energy conversion device and a 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 so-called switching power supply means that its regulating tube works in the switching state (the regulating tube of the series regulated power supply works in the amplification state), which is characterized by high working frequency, reaching above 10000 Hz; The ferrite core for transformer is small in size, which greatly reduces the copper consumption and iron consumption.

Switching power supply is relative to linear power supply, which does not mean that the power supply with' switch' is switching power supply.
