The average output of the bridge rectifier is about 64%of the input voltage. The Bridge-type full wave rectifier can convert an AC to DC by the mean of four diodes. The diodes are connected in such a configuration that the output peak voltage remains equal to the secondary of the transformer peak.
4. Smoothing Capacitor (Optional): To reduce ripple in the output voltage, connect a capacitor across the output terminals of the bridge rectifier in parallel with the load resistor. This capacitor assists in smoothing out the rectified waveform, resulting in a more stable DC output.
The Bridge-type full wave rectifier can convert an AC to DC by the mean of four diodes. The diodes are connected in such a configuration that the output peak voltage remains equal to the secondary of the transformer peak. In each half-cycle, a set of two diodes conduct and block the current alternately.
Bridge Rectifier Schematic: As the name suggests, the configuration of four diode connections forms a bridge.
