Electronic information technology products have a wide range of applications in our lives, and we are inseparable from electronic products both in life and work. Such as TVs, refrigerators, washing machines, LCD monitors, etc., are all essential electronic products in our furniture environment. The application of electronic products also includes instrumentation, medical equipment, security monitoring, etc. These electronic products are inseparable from switching power supplies. Without switching power supplies, some of them simply cannot function properly. It can be said that switching power supply is an indispensable power supply method in the electronic information technology industry.
The working conditions of the switching power supply are: to operate in a switched state, not a linear state. To ensure operation at high frequencies, low frequencies are not allowed. To ensure that the output is DC, AC is not allowed. During the use of the switching power supply, it is inevitable that damage will occur, and maintenance is required at this time. The first step in repair is to open the power supply case and check for an open circuit. Then smell it again, is there a mushy smell, is the detection element burnt?
