Bridge rectifier: The bridge rectifier circuit gives

The bridge rectifier circuit gives an output similar to that of a full wave rectifier . However, it consists of four diodes arranged in the form of a bridge as shown in Fig. 1. The diodes usually employed are the solid state diodes though vacuum tubes can also be used. Fig. 1: Circuit arrangement of a bridge rectifier . Working of Bridge Rectifier During the positive half cycle of the input supply, the upper end A of the transformer secondary becomes positive with respect to its lower point B ... A bridge rectifier is a type of full wave rectifier that converts AC signals into DC signals. An AC or alternating current flows in both directions, while a DC or direct current flows in one direction only. Therefore, by using both halves of the input, a bridge rectifier produces a smoother and more reliable DC output. A bridge rectifier is a circuit that allows a full alternating current (AC) waveform to pass using a standard transformer and four diodes.
