Step Up Chopper
Step Down Chopper
Procedure
Experiment Steps
Switch on the power for Kit. Set the potentiometer to minimum position. Switch on SW2 and observe the pulse across G.Check whether DC voltage is varying from 0-30V. Connections are made as shown in the circuit diagram. Now vary the frequency using to some point. Vary input voltage and note down the reading across load. Repeat from step6 for different values.
Note: If the connections are made wrong the kit may get damaged. Please switch off the kit when not in use.
