The use of switching power supply:
1. The function of the switching power supply is to convert a level of voltage into the current or voltage required by the user through different forms of architecture. The switching power supply has high conversion efficiency and can use a small size and light weight transformer. Therefore, the switching power supply will be smaller in size and lighter in weight than the linear power supply.
2. The switching transistor used in the switching power supply switches between the fully open mode (saturation region) and the fully closed mode (cut-off region). Both modes have the characteristics of low dissipation, and the conversion between switching will be higher. Dissipated, but for a short period of time, thus saving energy and generating less waste heat. The switching power supply itself does not consume power.
3. Switching power supplies are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps, communication equipment, audio-visual products, security monitoring, LED light bags, computer cases, digital products and instruments and other fields.
