Introduction of CHOPPER

chopper symbol image





















  • A chopper is a static power electronics device that converts fixed dc input to a variable dc output( controlled dc output) voltage power directly.

  • A chopper a simply a DC to DC converter.

  • Chopper is nothing but a high speed switch which connects and disconnects the load from source at a high rate to get variable or chopped voltage at the output.

  • Chopper can  increase or decrease the dc voltage level at its output side, so Chopper serves the same purpose  in dc circuit in case of AC circuit. So it is also know as Dc Transformer.

  • Chopper is also used like a Transformer as  step up or step down.

Hindi Meaning of CHOPPER


  • chopper basically ek power electronics device uai jo fixed dc ko variable dc mein convert karta hai

  • Yah ek Dc to Dc converter hai iska upyog transformer ke trah kiya jata hai

  • Yeh ek high speed switching device hai load ko source se connect aur disconnect karta hai jis se ki hame variable or chopped voltage mil sake.

Symbol of CHOPPER


It is a semi-conductor switching device.

 These devices are represented as a switch in a dotted box for simplicity. when it is closed current can flow in the direction of arrow only.

 Devices used in chopper:
For low power application: GTO, IGBT, POWER BJT.
For HIGH power application: Thyrister or SCR(Silicon Controlled Rectifier)


Application of CHOPPER


CHOPPER are user in Dc voltage regulator.

 Battery charging system

 DC voltage boosting

 Future automobile are likely to use chopper for theri speed control and breaking

 CHOPPER are widely used for traction motor control in electric automobile

 CHOPPER is used in marine lift.

Application Of CHOPPER



  • Save power

  • It require less maintenance , 

  • fast response

  • It is highly efficient and smooth acceleration


  • It is a semi-conductor switching device. so its symbol are  similar as a switch
