Question 2
A transistor is used as a switch and the waveforms are shown in Figure 2. The parameters are
Vcc = 225 V, VBE(sat) = 3 V, IB = 8 A, VCE(sat) = 2 V, Ics = 90 A, td = 0.5 µs, tr = 1 µs, ts = 3 µs, tƒ
= 2 μs, and f
10 kHz. The duty cycle is k 50%. The collector- emitter leakage current is
ICEO = 2 mA. Determine the power loss due to the collector current:
