full bridge rectifier current flow during positive half cycle

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 secondary of transformer peak. In each half cycle, a set of two diodes conduct and block the current alternately.
