Question 9
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 = 38µs, t0 = 53 µs and fs =10 kHz, k = 40 % and ICEO = 2 mA. The average power loss in the transistor due to the base current are equal to:
