2-13. An alternative circuit for energizing an inductor and removing the stored
energy without damaging a transistor is shown in Fig. P2-13. Here VCC  12 V,
L  75 mH, and the zener breakdown voltage is VZ  20 V. The transistor
switch opens and closes periodically with ton  20 ms and toff  50 ms.
(a) Explain how the zener diode allows the switch to open. (b) Determine and
sketch the inductor current i
L(t) and the zener diode current iZ(t) for one
switching period. (c) Sketch (p)(t) for the inductor and the zener diode.
(d) Determine the average power absorbed by the inductor and by the
zener diode
