Switching power supply, also known as switching power supply or switching converter.
It is a high-frequency electrical energy conversion device and a type of power supply. Its function is to convert a precise voltage into the voltage or current required by the user through different forms of architecture.
The so-called switching power supply refers to its adjustment tube working in the switching state (the series stable power supply adjustment tube working in the amplification state), which is characterized by a high operating frequency of over 10000 Hz; Transformers use ferrite cores with small volume, greatly reducing copper and iron losses. Switching power supply is relative to linear power supply, and it does not mean that a power supply with a 'switch' is a switching power supply.
