What is the function of switching power supply

Switching power supply also plays a certain role in the process of use, so what is the main role?

1、 What is the function of switching power supply

1. The main function of switching power supply is to cut high energy into countless low energy, and then transmit it to the output terminal, and the output terminal will also feed back the input terminal through the output voltage, which can achieve the effect of stabilizing the output voltage.

2. In addition, the heating capacity of the switching power supply is relatively low, because it can reduce the voltage by converting excess energy into heat, and the efficiency of the switching power supply is relatively high.

2、 Main characteristics and working conditions of switching power supply

1. The switching power supply is characterized by its small size and very light weight, mainly because it has no transformer, so it is very convenient to use.

2. In addition, the switching power supply has the characteristics of high efficiency but low power consumption. The efficiency can basically reach 70% of 60%, but the common linear power supply is only 30%~40%. Compared with the linear power supply, the working efficiency of the switching power supply is higher.

3. When switching power supply is working, it is in a switching state, not in a linear state.

4. And the switching power supply output is DC, not AC.
