Classification of switching power supply
According to the connection mode of switching devices in the circuit, switching power supply can be divided into three categories: series switching power supply, parallel switching power supply and transformer switching power supply.
Among them, transformer switching power supply can be further divided into push-pull type, half bridge type, full bridge type and so on. According to the phase of excitation and output voltage of transformer, it can be divided into forward excitation type, flyback type, single excitation type and double excitation type.


The difference between switching power supply and common power supply
The general power supply is linear power supply, linear power supply, which refers to the power supply of regulating tube working in linear state. But in the switch power supply, the switch tube (in the switch power supply, we generally call the regulator switch tube) is working in two states: On - resistance is very small, off - resistance is very large.
