AC Switching Power Supply

What is an AC Switching Power Supply?

Most people have no idea what an AC switching power supply is, the only thing that they know is that they need one. The job of an AC switching power supply is supposed to convert AC from the wall socket to DC so that your appliance can use it. Many times a problem can come when the AC power supply is no longer giving power to the appliance. If you find that this is happening then you might want to try a few things to make sure of what the problem is.

AC Switching Power Supply

Here is What to Do

The first thing that you need to do is to plug the power supply that is in the wall socket, then measure the DC output, take special note on if it is steady or not. Then you need to unplug the AC switching power supply and check and see if you have any bad capacitors. If you find that you do then you need to make sure that you replace them. This will take some skill and if you don't know how to do it then you may want to call a professional.

Then you will need to measure the filter's resistor's value, if the resistor value is off or you find that the inductor is shorter, then you might have a problem. You will then need to turn the DMM and read what the DC voltage is and try to measure the output of the rectifier stage. Remember that it will have some fluctuation because the reading will be a series of half waves.

If This All Seems Greek To You

The important thing that you need to remember when dealing with an AC switching power supply is that you will need to make sure that you know what you are doing. If you find that you have no idea what you are doing then you don't need to do anything. The best idea is to try and call someone that does know exactly what they are doing and wait for them to come and help you.

The last thing that you want to do is make the problem worse or risk hurting yourself. When you do anything that has to do with electrical problems then if you aren't one hundred percent sure that you know what you are doing then you need to think about it, before you do anything. You need to remember that you want to stay safe more than anything else.

AC Switching Power Supply

No matter what kind of appliance you are going to be using then you will need an AC switching power supply. The problem is that most people are not sure when this is what is causing the problem with their appliance or if there is a problem with the power supply. That being the case then being able to understand that there is a difference can help you to try and understand the problem that you are looking at.
