mosfet bridge rectifier circuit

This circuit gives an overview of the working of a full-wave rectifier. The bridge rectifier is constructed by using 4 diodes in the form of a Wheatstone bridge which is fed by a step-down transformer. But bridge rectifier consists of four diodes, hence the amount of power waste will be twice of the power waste in the above circuit with single diode.
