Question

Draw and explain the working of a bridge rectifier ckt and draw its relevant waveforms also. Drive the expression for its average, rms, currents and ripple factor. A bridge rectifier with $120\text{ vrms}$ sinusoidal input has a load resistance of $1\text{ k}\Omega$

(i) What is the DC voltage available at the load

(ii) What is the required PIV rating of each diode

(iii) Find the max current through each diode

(iv) What is the ripple facto of the ckt?

(Assume that $V_r = 0.7\text{v}$, & $r_f = 0$)
