Analysis of key points in switching power supply design

Electronic products can be seen everywhere in life, the most common one is power supply. Now our life can be said to be inseparable from power supply. Lighting needs power, watching TV needs power, air conditioning needs power... So if we are decorating a new house, the most important thing cannot be ignored. Power, if there is no power in the house, you can't do anything. Therefore, we need to pay special attention when designing the switching power supply to prevent circuit problems. So, what should you pay attention to when designing a switching power supply? Pay special attention to the following five aspects.

1. Wiring

The wiring design requirements are very strict in the switching power supply design, and they must be done well to pass the test. If the designer fails to handle the wiring work in the early stage of design, there will be great safety risks in future electricity use. Therefore, I suggest that you pay attention to the actual condition of the wiring when purchasing a switching power supply to prevent irreparable damage.

2. Element layout

Component design is also very important. When designing, you must follow physical design principles and do not change the position of components based on your own ideas to prevent short circuit accidents. In addition, designers should also check the quality of the product themselves when purchasing components.

3. Parameters

In the design of switching power supply, we must understand every structural detail, especially the parameters, so that we can give specific instructions for future use. The detailed parameters also facilitate later testing of the switching power supply, which will also save some time.

4. Check

After each switching power supply is designed, it must undergo strict inspection before production. Only through inspection can the availability and applicability of the switching power supply be determined, so as to price the switching power supply. When inspecting, we first start with the circuit, detect the real working environment of the switching power supply, and in what environment it is most suitable to work and operate, to avoid circuit accidents in certain environments. Safety is our first concern, so we need Carefully inspect the switching power supply.

5. Choose the appropriate power

In order to extend the life of the switching power supply, I recommend choosing a model with a 30% output power rating. If the system requires a 100W power supply, it is recommended to choose a model with an output power rating greater than 140W, and so on to effectively extend the life of the power supply.

After reading the above introduction, you should also know what you need to pay attention to when designing a switching power supply. When designing a switching power supply, special attention must be paid to the five aspects mentioned above. Otherwise, if there are problems during the design, it will have a great impact on the future use of the power supply. The above are several aspects that need to be paid attention to when designing a power supply, which will be helpful to beginners.
