Procedure

CRO Settings

  • Time (X) Axis : 5ms/div
  • Voltage (Y) Axis: 20V/div
  • Probe :1:10 CRO Probe is suitable one.

Initial Settings

  • Ensure the 230V Power Supply is in proper with Tester.
  • Ensure the CRO is working properly with probe checking and proper ground line axis.

Experiment Steps

  • The connections are made as per the circuit diagram given above.
  • The R Load must be 60W bulb or 200ohm/2A Rheostat. The Load is 120mH/2A.
  • When the load is R heostat, then it must be in maximum position.
  • Turn on the SW2 and observe the waveform across between G1&K1, G2&K2, G3&K3, and G4&K4. And ensure it is like triggering pulse given in model graph.
  • Turn ON SW1 and observe the waveform across the R load and RL Load.
  • Measure the X-axis time interval of ON time of Load Voltage and OFF Time of Load Voltage.
  • Adjust the value of Firing angle and note down the load voltage and current.
  • Repeat the step 6.
  • Repeat the experiment for different values of α and note down Vo.

Note: *If the connections are wrong the kit will get damage. *The load must be R and RL. Do not connect L Load alone.
