Interchangeable Plugs AC/DC

                 The power adapter ground effect of the power adapter is the transformer and the rectifier. Home AC power is 220v, and our computer is DC 12v (as if), so it is possible to be sure that the power adapter is the transformer and rectifier. Then the adapter is a transformer, we should know that the AC 220v through Transformers transformer, through the rectifier to DC, here is a consumption, and these consumption will be converted to heat, so the power adapter will be normal fever. The transformer is made of silicon steel sheet, the transformer after power, the production of magnetic flux, magnetic flux will incur a force between the silicon steel, resulting in a buzzing sound, this is normal. But the sound of the earth is not normal, a lot of reasons: 1, AC voltage instability. 2. Chip breakage. 3. Short circuit between turns. 4. The component is damaged. Wait a minute.Interchangeable Plugs AC/DC 

               The application of power adapter in consumer electronics products is very extensive, providing the output power of most of them within 100 watts, the market demand for rapid growth. such as electric bicycle battery charger, small size LCD TV, notebook computer, printer, DVD player and set-top box and so on are applied. The early power adapter mostly selects the linear transformer, along with the consumer electronic product to the power adapter has the high efficiency, the wide input voltage range request, as well as the copper, the iron and the human cost increase, this kind of power adapter inside the original linear transformer mostly gradually by the switching power supply replaces. Power adapter characteristics of the Power converter (both AC-DC), from alternating current to DC power, and then through the computer, it is not able to protect the computer, but the computer inside a storage device (also called a charger), so in the power outage can protect the computer.Interchangeable Plugs AC/DC 

              Switching power supply and adapter are switching power supply, is composed of high-frequency switch tube and its control circuit. Adapter power supply is a voltage regulator switching power supply, switching power supply charger is equipped with floating charging function, the voltage is with the current smaller and larger, to the end is only the voltage and no current. The characteristics of the power adapter are: Power converters (both AC-DC), from alternating current to DC, and then through the computer, it is not able to protect the computer, but the computer has a storage device (also called a charger), so in the power outage can protect the computer.Interchangeable Plugs AC/DC
