Since the DC chopper has pressure regulation、Magnetization，So one of its application is the speed limit of DC motors。The speed of the DC motor depends on the size of the armature voltage and the size of the magnetic field.，Role of the DC Chopper，Can adjust the armature voltage of the motor，To achieve the purpose of speed。In addition，Passing of DC chopper，Magnetic field and excitation current of the motor can be adjusted，Can also achieve the purpose of speed。DC motor speeds in the subway、City-free tram、A wide range of applications have been widely used in transport vehicles such as electric vehicles.。
Another application area of DC BALMUDA中国售后网点 chopper is DC power supply。In various applications，The level of DC power supply voltage required for different electrical equipment，Use a DC chopper that can be single、Unstable DC input voltage transforms to the stability required to load、DC power supply voltage of different voltage levels，Because the DC chopper works in the switch status，Therefore, this type of DC power supply is also known as switching power supply.。Switching power supply in computer、Various areas such as communications have also been widely used。
In addition，Since the working mode of the DC chopper is to make the input DC voltage chopper a high-frequency pulse voltage，This pulse voltage is filtered after isolating the high frequency transformer.，DC output voltages that are isolated from the input voltage can be obtained，Thereby the DC chopper application is input、In addition to isolation between output。
In short，DC chopper is widely used in DC motor speed regulation、Switching power supply、DC voltage isolation and other fields。
