For switching power supply designers, three types of transients that affect the power supply at the beginning must be protected: 1. Transient voltage (inductive load) caused by load change; 2. Transient voltage introduced by power line; 3. Transient voltage generated inside the switching power supply. Typical components that need protection in the power supply are: 1. High back pressure switching transistor (VMOS tube) 2, high voltage rectifier (high voltage flow rectifier diode) 3, the output rectifier (output high current rectifier diode) 4, internal control circuit (pulse width modulator, etc.) An example of the application of TVS in a typical switching power supply, as shown in the figure, there are a total of eight TVS tubes, each protecting their own objects, of course, the characteristics of the eight TVS tubes are also different, from "breakdown voltage", "maximum pulse peak power", "pulse The peak current "to" the clamp voltage" and so on are different. The switching power supply used by an HP company in the United States can see the number and condition of all transient voltage suppression diodes in the power supply. The application of TVS in foreign countries is very common, and the number is also very large. It can be seen that TVS is crucial to improve the reliability of the whole application.
