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

2-13. Ny faritra hafa noho izay manome hery ny inductor sy ny fanesorana ireo voatahiry
hery tsy nanimba ny transistor no hita ao Fig. P2-13. VCC Tompo? 12 V,
L? 75 MH, ary ny faharavan'ny zener VZ matanjaka? 20 V. Ny transistor
jiro manokatra na manidy amin'ny Nisy fotoana taonina? 20 MS sy ny toff? 50 MS.
(a) Hazavao ny fomba diode zener payback avy amin'ny jiro hanokatra. (B) Farito sy
kisary tsotsotra aho amin'izao fotoana izao ny inductor
L (T) sy ny zener diode Iz amin'izao fotoana izao (t) fa iray
vanim-potoana ara. (C) Sketch (p) (T) ho an'ny inductor sy ny zener diode.
(d) Farito ny hery eo ho eo ny inductor variana sy ny
zener diode
