The Difference Between The Battery Charger And The Switching Power Supply

  The difference between the Battery Charger and the switching power supply

  1, the Battery Charger is a power supply, and now most of the market Battery Charger to do the use of switching power supply. This is because the switching power supply conversion efficiency is high, small size, low cost.

  2, switching power supply is a kind of power supply, is to achieve a direct change DC DC means and methods.

  Switching power supply and Battery Charger are power, the Battery Charger can be used to do the switching power supply can not do switching power supply. But most of the Battery Charger or the use of switching power supply to achieve the way, after all, switching power supply in this area has its advantages.

  We said that the switching power supply is mainly responsible for the DC into high-frequency pulsating direct current, and then through the high-frequency switch through the transformer buck, through this step can remove the high-frequency AC part, so that you can get low-voltage direct current, and the computer The most important part of the switch circuit, so the computer power supply is also commonly called switching power supply, in fact, popular call switch power is the computer above we say "transformer".

  We use the Battery Charger is not the same, the Battery Charger is generally 220V AC power into a more appropriate DC voltage, according to the type of rechargeable battery, will increase a charge management circuit, and then you can charge the battery to work , Although the Battery Charger can be used as a switching power supply, but not so the Battery Charger is a switching power supply.

  In fact, switching power supply is used to make the Battery Charger, switching power supply in many ways can be used, but the Battery Charger is only charge the battery charge work. Battery Charger according to the nature of the rechargeable battery in the charge of the above requirements are different. Now the Battery Charger has many types, such as constant current constant voltage Battery Charger, travel Battery Charger and so on.
