Problems solved by technology

[0002] At present, electronic products are developing rapidly. The AC-DC power module products on the market are usually large in size, and the input range of traditional power frequency AC-DC power supplies is limited. It is necessary to convert the mains AC input voltage into a lower AC voltage. When the rectification becomes the required DC voltage, the AC input overvoltage and undervoltage protection of the AC-DC power supply plays a very important role. It can prevent the power supply from working when the AC input voltage exceeds the allowable operating range of the power supply to protect the power supply. , to prevent failures caused by over-voltage and under-voltage, the existing AC-DC power supply has the disadvantages of large volume, heavy design, backward circuit structure, low efficiency, poor anti-vibration performance, and easy damage
