When you are a beginner to repairing an SMPS, you need to get a head start in the art of fixing faulty power supplies. It is not an easy thing to do it because the structure of the SMPS is complicated and cannot be understood by all the people. Therefore, it is very important for you to know about the basics of the SMPS and for this, you will have to search over the information over the internet.
There are not few but plenty of things that you are supposed to know for repairing an SMPS as it is complicated machinery. There are different parts in an SMPS that you are supposed to know about in order to repair it in the best way possible. In the forthcoming paragraphs, we are going to explain some necessary details about repairing the SMPS, so that you can easily repair it.
When there is no output, the fuse is good
Many people think that when there is no output from the SMPS, refuse might not be working, but it is just a myth. It is not necessary that when output is on, the fuse is broken. There can probably be a problem with semiconductors, and you need to check them if you are getting no output from the SMPS. It can be easily corrected by replacing the semiconductors with the new ones.
Partial working of the SMPS
Another big problem with the SMPS working can be partial functionality. There are various functions, or we can say partitions in the SMPS, and it can be a serious problem when some of them are working while others are not. Make sure to check which party is not working and take necessary action for those parts only.
The electrolyte the capacitors are sometimes the main cause of SMPS problems. When you buy cheap designs in the electrolytic capacitors, the thermal dissipation is very close to the limit. Therefore, make sure to replace the cheap capacitors with good quality ones.
