STEP 1: Drag and drop the components in the workspace to create the circuit.

Nos of required components:

DC Source - 1, Square Wave – 1, IGBT – 1, Diode - 1, Inductor - 1

Switch - 1, Ammeter - 3, Resistor - 1, Voltmeter – 2, Ground – 1

STEP 2: Make the connections as per the instructions given below:

(a) (01-03, 04-05, 06-07)

(b) (08-10, 09-13, 11-12)

(c) (12-14, 15-13, 13-16)

(d) (13-02, 06-17, 18-19)

(e) (20-21, 22-23, 24-13)

(f) (20-25, 26-13)

Note: Click on the wire to delete the connection.

STEP 3: Click on the CHECK button to check the connections.

Note: Right click on the component to open the dialog box to edit the properties of the component.

STEP 4: Input the values for all the required components (DC Source, Square Wave, Inductor or Resistor) and the waveform will get plot automatically.

STEP 5: Now, Click on the ADD button to insert the reading into the observation table.

STEP 6: Now, you can input different values as per your requirement to get the desired waveform.

STEP 7: Repeat Step 5 to again insert the reading into the table and now repeat Steps 6 to 7 to take more readings.

STEP 8: Click on the PRINT button to take out the print of the webpage.

STEP 9: Click on the RESET button to reload the webpage.
