प्रश्न
With the help of a circuit diagram, explain how a full wave rectifier gives output rectified voltage corresponding to both halves of the input ac voltage.
उत्तर
A full wave rectifier is a circuit configuration that transforms both half cycles of input alternating current (AC) to direct current (DC). As a result, a full-wave rectifier is significantly more efficient than a half-wave rectifier. A full wave rectifier is a device that converts both half cycles of the input supply (alternating current) to direct current (DC). There are two techniques to build a full wave rectifier. The first technique employs a centre-tapped transformer and two diodes.
The ends of the secondary transformer are connected to the p-side of the two diodes in this configuration.
The two-diode circuit in Figure produces output rectified voltage that corresponds to both the positive and negative halves of the alternating current cycle. It is therefore referred to as a full-wave rectifier.
The output is measured between the common point of the n-side diodes and the middle of the transformer's secondary after the n-side diodes are coupled together. As a result, the transformer is referred to as a centre-tap transformer since it has a secondary that is equipped with a centre tapping for a full-wave rectifier.
