The main purpose of Switching power supply 30V

Introduction :Switching power supply 30V is different from linear power supply. Most of the switching transistors used by switching power supply are switched between fully open mode (saturation area) and fully closed mode (cut-off area).

Switching power supply 30V is different from linear power supply. Most of the switching transistors used by switching power supply are switched between fully open mode (saturation area) and fully closed mode (cut-off area). These two modes have the characteristics of low dissipation. Switching The conversion between will have higher dissipation, but the time is very short, so it saves energy and generates less waste heat. Ideally, Switching power supply 30V itself will not consume power. Voltage regulation is achieved by adjusting the turn-on and turn-off times of transistors. On the contrary, in the process of generating the output voltage of the linear power supply, the transistor works in the amplification area and consumes power itself. The high conversion efficiency of Switching power supply 30V is a major advantage, and because the switching power supply has a high operating frequency, a small-sized and light-weight transformer can be used, so the switching power supply is also smaller and lighter than the linear power supply .

If the high efficiency, size and weight of the power supply are the key considerations, the switching power supply is better than the linear power supply. However, the switching power supply is more complicated, and the internal transistors will switch frequently. If the switching current has not been processed, noise and electromagnetic interference may be generated and affect other equipment. Moreover, if the switching power supply is not specially designed, its power factor may not be high.
Switching power supply 30V products are widely used in industrial automation control, scientific research equipment, LED lighting, industrial control equipment, communication equipment, electrical 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 strips, computer cases, digital products and instruments and other fields.
