A transistor is used as a switch and the waveforms are shown below. The parameters are given as follows: VCC = 100 V, VBE( (sat) = 4 V, IBS = 10 A, VCE( sat ) = 2 V, ICS = 50 A, td = 0.4 μs, tr = 1.6 μs, ts = 3 μs, tf = 4 μs, tn = 38 μs, t0 = 53 μs and fs = 10 KHz, k = 40% and ICEO = 2 mA. The average losses during the delay time td = mW
