Procedure

1. For Circuit formulation:

a) Form the circuit of push-pull converter by dragging the mouse from one terminal to the other.
b) After completion click on ‘Check Connections’ to verify the circuit connections.
      • If ‘Correct Connections’ box appears, click on ‘Completed Circuit Diagram’.
      • If ‘Incorrect Connections’ box appears, remove the connections in RED colour and reconnect. (use ‘Hint’ box for reference.)
c) Click on ‘Completed Circuit Diagram’ to go begin the experiment.

2. For plotting Waveforms:

a) Set the value of V_G.
b) Set the load resistance (R) using the rheostat slider.
c) Set the turns ratio N_P : N_S.
d) Set the duty ratio D = D₁ = D₂ using the duty ratio slider.
e) Press ‘Record Waveforms’.
f) Press ‘Record Values’ to obtain various quantities.
g) Use ‘Reset All’ button to restart the experiment.

3. For ideal voltage gain plots:

a) Click on ‘Make connections’ icon.
b) Set the value of V_G.
c) Set the turns ratio N_P : N_S.
d) Set the load resistance (R) using the rheostat slider.
e) Set the duty ratio D = D₁ = D₂ using the duty ratio slider.
f) Press ‘Record’.
g) Vary the duty ratio to fill up the highlighted table.
h) Click on ‘Plot’.
i) Plot the graphs for the other two loads by repeating step (1) then steps (4) to (7).
      • Use ‘Delete’ button to remove the latest entry in any table.
      • Use ‘Reset’ button to remove all the entries of the table that is being filled.
      • Use ‘Reset All’ button to restart the experiment.

4. For practical voltage gain plots:

a) Set the value of V_G.
b) Set the turns ratio N_P : N_S.
c) Set the load resistance (R) using the rheostat slider.
d) Set the duty ratio D = D₁ = D₂ using the duty ratio slider.
e) Press ‘Record’.
f) Vary the duty ratio to fill up the highlighted table.
g) Click on ‘Plot’.
h) Plot the graphs for the other two loads by repeating steps (3) to (7).
      • Use ‘Delete’ button to remove the latest entry in any table.
      • Use ‘Reset’ button to remove all the entries of the table that is being filled.
      • Use ‘Reset All’ button to restart the experiment.

5. For Efficiency:

a) Set the value of V_G.
b) Set the turns ratio N_P : N_S.
c) Set the duty ratio D = D₁ = D₂ using the duty ratio slider.
d) Set the load resistance (R) using the rheostat slider.
e) Press ‘Record’.
f) Vary the load resistance (R) to fill up the table.
g) Click on ‘Plot’.
      • Use ‘Delete’ button to remove the latest entry in any table.
      • Use ‘Reset All’ button to restart the experiment.

6. For component stresses:

a) Set the value of V_G.
b) Set the turns ratio N_P : N_S.
c) Set the load resistance (R) using the rheostat slider.
d) Set the duty ratio D = D₁ = D₂ using the duty ratio slider.
e) Press ‘Record’.
      • Use ‘Reset All’ button to restart the experiment.
