What do I need to pay attention to when designing a switching power supply?
Now our life can be said to be inseparable from the power supply, lighting needs power, watching TV needs power, air conditioning needs power ...... So if we are renovating a new house the most important thing that can not be ignored is the power supply, if there is no power supply in the house, it can be said that nothing can be done. Therefore, we need to pay extra attention in the design of switching power supply, can not let the circuit problems. So, switching power supply design need to pay attention to what? I think the following five aspects require extra attention.
1, wiring
Wiring design requirements in the switching power supply design is very strict, to do a good job to pass. If the designer in the design of the pre-design did not deal with the work of wiring, then the future of electricity will be a great security risks. So here I suggest that we should pay attention to the actual situation of the wiring when buying switching power supply to
prevent irreparable damage.
2,Element layout
There is also a very important element design, in the design must follow the physical design principles, do not change the position of the element with their own ideas, in order to prevent the occurrence of short-circuit accidents. In addition, the designer should also check the quality of the product when purchasing the meta device.
Parameters
Inside the switching power supply design, we must understand every detail of the structure, especially remember the parameters, so as to give the future use of specific instructions. Detailed parameters are also convenient for the later use of the switching power supply. Detailed parameters are also convenient for later testing of switching power supply, which will also save part of the time.
4,Check
After the design of each switching mode power supply, it is necessary to go through strict inspection before production, only through the inspection can determine the usability and applicability of the switching mode power supply, so as to carry out the pricing of the switching mode power supply. Pricing of the switching power supply. When checking, firstly start from the circuit, test the real working environment of the switching power supply, in what kind of environment is the most suitable to avoid the operation under certain environment. To avoid circuit accidents in certain environments, safety is our first concern, so we need to carefully check the switching power supply.
5,Choose the right power
In order to make the life of the switching power supply longer, I recommend that when you choose to use 30% of the output power rated models. If the system requires a 100W power supply, then it is recommended to select a power supply larger than 140W. If the system requires a 100W power supply, then it is recommended to select a greater than 140W output power rating of the model, and so on to effectively improve the life of the power supply.
After reading the above, you should also know the switching power supply design matters needing attention. The design of switching power supply must pay extra attention to the above The five aspects mentioned above, or design problems, the use of power supplies in the future will have a considerable impact.
