#Watch and do it yourself #Solve all doubts #Why change from AC to DC #How many amps of power Hello, today I will demonstrate how to connect a 2-wire transformer from alternating current, also known as AC, to direct current, also known as Dc. Converting power from Ac to DC requires the use of diodes and capacitors to obtain a more stable and smooth signal. First, let's understand that a transformer's function is to convert electric current to a lower or higher level, depending on its use. In this clip, we will convert the current to a lower level. Therefore, we must feed electric current into the primary winding, which will induce induction between the iron core and the secondary winding. The resulting voltage depends on how many turns the secondary winding can be wound. The more turns, the more voltage. But don't worry, because most transformers sold in general markets come in various sizes and values, covering the voltage we need, such as 6v, 9v, 12v, 15v, 24v, depending on our use. For this transformer, the output value will be around 15V AC. Let me emphasize that this transformer cannot convert alternating current to direct current. The 15V that is obtained will be alternating current. We will use diodes to connect to make the current flow in the same direction. We will use 4 diodes to get full current on both sides and separate the positive and negative terminals. If you still do not understand why we need 4 diodes, let me explain to you. Because the electricity that we convert is still alternating current, which will flow alternately on both wires at the same time. If we use only one diode, we will get only half of the positive terminal A voltage when the wave bounces up. It will continue like this, and the voltage will only be half. Therefore, we need another diode connected in parallel to trap the current on wire B and force it to fill the missing part of the positive terminal. The current will be full on the positive terminal. Then, what are the other two diodes for? When we have full current on the positive terminal, we need another terminal to complete the circuit, which is the negative terminal. We will use the advantage of diodes, which is to reverse the polarity to prevent the positive current from passing through. But the negative current passes easily, we will get the negative pole. At this point, friends, you start to understand, right? How do positive and negative poles occur? But that's not all. Because if you notice, the current is still a wave like the sea. Because it is affected by the frequency. Therefore, a capacitor must be used to filter the electric current to be smoother. The capacitor has two poles. It is easy to notice that the negative pole will have a clear negative symbol. Then connect the negative leg of the capacitor to the negative DC pole. The other leg is connected to the positive DC pole. When the capacitor is connected, the capacitor will help filter out high frequencies. And help store and discharge the charge smoothly. That's it for the method of converting AC to DC. In addition to the diodes as shown in the picture, there is another type of diode that is more convenient to use and works the same, which is the bridge diode. The bridge diode will have a symbol on the side of the leg. Friends just connect the input and output according to the symbol. Let's get to the most popular question. The question is, why convert electricity to DC? The answer is because most electronic devices It will work more stably and better in DC mode because it is more constant. Question: Can I use a diode or capacitor? The answer is yes, you can. Just connect it through the transformer, but the electricity will be just AC current. Question: How many amps does the transformer in the clip have? The answer is: Looking at the size of the coil and the small core that is wound, it should not exceed 1A. Question: If I want higher amps, I must use a larger coil to wrap the secondary side. A small transformer like this has no way that the wire can wrap a full circle with a large coil. Also, the iron core called EI is not suitable. Therefore, if I want higher amps, the transformer I use must be larger. To get a current of 5 amps, the transformer is very large. Most people who want high amps will switch to switching power supplies.
