Which of the following is the most suitable device for a dc-dc converter?

Which of the following is the most suitable device for a dc-dc converter? Correct Answer GTO

DC to DC converters (DC Choppers):

  • A dc chopper converts dc input voltage to a controllable dc output voltage.
  • For lower power circuits, thyristors are replaced by power transistors.
  • Choppers find wide applications in dc drives, subway cars, trolley trucks, battery driven vehicles, etc.


The most suitable device for a chopper is GTO.

The different devices used in chopper are:

Low power application: GTO, IGBT, Power BJT, Power MOSFET etc.

High power application: Thyristor or SCR.
