Explain Center-tapped full wave rectifier with the help of circuit diagram and draw input output waveforms.

Operation : During positive half cycle of an AC supply, D1 will forward biased and current starts flowing through load. The output voltage is equal to +Vs. During negative half cycle of an AC supply, D2 will forward biased and current starts flowing through load. The output voltage is equal to +Vs. In this pulsating DC waveform will be obtained at the load.
