Question
Draw and explain the working of a Centre-tapped full wave rectifier with reference to different waveforms. Drive the expressions for its DC value of voltage, ripple factor & rms value of voltage.
A centre-tapped full wave rectifier has $R_L = 1\text{ k}\Omega$. Each diode has a Forward resistance $r_f = 10\Omega$. The voltage across half the secondary winding is $220 \text{ Sin } 314t$. Find Peak, average, & rms values of current. Also find PIV rating of each diode & ripple factor of the rectifier. (20)
