INFE242 ELECTRONICS
4-) In the half-wave rectifier in Figure 4 diode D is ideal. The input V, is a 50-Hz sinusoidal voltage with peak value V, (v,(1) = V, sin(@t) V ). The rectifier feeds a load which draws constant current /, from the rectifier. (a) Derive an expression for the ripple voltage V, in terms of I,, C and V, (Hint: After the diode turns off att, , the capacitor discharges with a constant discharging current i̟ = -I̟. Also the discharging time (from t, to t, +T) can be approximated by the period of the sine wave T = Express dv / dt in terms of V, ) (b) With 1, =0.1 A, C = 200 µF, V, = 100 V calculate V, .( (c) Calculate the conduction angle of the diode DAt . (:“ (Hint: It may help to review the derivation of wAt for the resistance load case) - Vc V, Figure 4 ,+T
