In the diode-bridge full-wave rectifi er of let vS be a 60-Hz, 18-V (rms) ac voltage, and let the load draw 10 mA of current. (a) Specify C for an output ripple of 1.5 V. (b) Assuming VD(on) 5 0.8 V, fi nd VO, iD(max), iD(avg), TON, and PIV. (c) What happens if D4 blows out and becomes an open circuit, everything else remaining the same? Recompute all the parameters that change as a consequence of D4’s failure, compare, comment.
