Full Wave Bridge Rectifier With Capacitor And Zener Diode. The knee in the reverse bias region in fig. And that s because of its high break down voltage typically of the order of 200 to 1000 volts which is obvious.
A bridge rectifier with an efficient filter is ideal for any type of general power supply applications like charging a battery powering a dc device like a motor led etc etc. In each half cycle a set of two diodes conduct and block the current alternately. It uses both halves of the waveform in the transformer winding and as a result reduces heat losses for a given level of output current when compared to other solutions.
The dark line is the filtered output while the thinner line is the unfiltered output.
The dark line is the filtered output while the thinner line is the unfiltered output. We use the diodes namely a b c and d which form a bridge circuit. The bridge type full wave rectifier can convert an ac to dc by the mean of four diodes in such configuration that the output peak voltage remains equal to the secondary of the transformer peak. Full wave rectifier output waveforms.
