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.
Merits: The circuit has the trend to stabilize operating point against changes in temperature and β-value. Demerits: In this type of circuit, to keep I C independent o
