8) Connect a voltmeter across the gate -emitter and another voltmeter across the co 11 ector -emitter terminaLs
9) Switch ON the230V AC supply
10) Fix tlie gate- emitter voltage (V GE) using the pot,
11) Smoothly vary the Collector-Emitter (VCE) Yoltage by varying tlie Pot> till tlie IGBT tums ON. Notę tlie Yoltmeter and Ammeter tle) readings
12) Once turned ON. Increase tlie Vce and Notę change in current Ic
13) Repeat tlie steps 5 & 6 for different values of Vce
