DC chopper
This is one stage conversion device which is used for direct conversion of fixed de voltage at a level to an adjustable dc voltage at another level.
Figure DC Chopper
Chopper is high speed on/ off semiconductor switch is represented by a switch SW with an arrow as shown no current will flow if the switch is off and when it is on current will flow in the direction of arrow only.
