With the help of a circuit diagram, explain the working of a full wave rectifier. Depict the input and output waveforms.

Explaining the working with the help of circuit diagram Depicting the input and output waveforms \[1 / 2+1 / 2 \] Let the input voltage A with respect to the centre tap at any instant is positive. At that instant, voltage at B being out of phase will be negative. So, diode $\displaystyle \mathrm{D}_{1}$ gets forward biased and conducts (while $\displaystyle \mathrm{D}_{2}$ being reverse biased is not conducting). Hence, during this positive half cycle we get an output current. When voltage at A becomes negative w.r.t. centre tap, the voltage at B would be positive. In this part of the cycle diode $\displaystyle \mathrm{D}_{1}$ would not conduct but diode $\displaystyle \mathrm{D}_{2}$ would be giving output current.
