Question

The half-wave rectifier in Figure 2–19 has a 250-μF filter capacitor and a 1.5-kOhm load. The ac source is 120 V rms with frequency 60 Hz. The voltage drop across the silicon diode is 0.7V. Assuming light loading, find

(a) the dc value of the load voltage;

(b) the peak-to-peak value of the ripple

(c) the %-ripple

(d) plot vin(t), vR(t) (output without the filter cap) and vL(t) (output with the filter cap) all on the same graph

FIGURE 2-19 When load vc(t) = vL(t) resistance R, is connected across the filter capacitor, the capacitor charges and discharges, creating a load voltage that has a ripple voltage superimposed on a dc level. v(t) ripple voltage VPR Vpp Vdc Vpr waveform with filter capacitor disconnected waveform with filter capacitor and load resistance connected ´discharge (load) charging load resistance current, when input pulses are current, Ewhen input pulses are e; RL present absent
