What can a switching power supply be used for? Detailed some answers

Switching power supply can be used: 1, the role of the switching power supply is a bit of voltage, through different forms of architecture conversion into the user side of the current or voltage demand. Switching power supply high conversion efficiency, can use small size, light weight transformer, therefore, switching power supply will also be smaller than the size of the linear power supply, the weight will be lighter. 2, switching power supply using the switching transistor in the full-open mode (saturation area) and full-closed mode (cut-off area) switching between the two modes are characterized by low dissipation, switching between the switching will be a higher dissipation, but the time is very short, therefore more energy saving. Therefore, it is more energy efficient and generates less waste heat. Switching power supply itself does not consume electricity. 3, switching power supply is widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD monitors, LED lamps and lanterns, communication equipment, audio-visual products, security monitoring, LED light bags, computer chassis, digital products and instruments and other fields.
