RL which is connected between the terminals C and Current (DC). It uses four diodes in a bridge topology for it to be able to rectify both the positive and the negative half-cycles of the AC input. This accommodates the polarity shifts of the AC power but ensures that each AC cycle's positive and negative peaks exit at the same point on the bridge. as ripple factor. The advantage of using Bridge rectifier is that no centre tapping is required. The Please take all required safety precautions while handling the bridge rectifier IC. It is also used in AM radio. This causes the tapped full-wave rectifier, Alternating How does a Bridge Rectifier work? D.
