On the other hand, full-wave rectifier improves on the conversion efficiency of AC power to DC power. Half-wave rectifiers can be used, but they are highly inefficient in converting AC power to DC power. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. In a Full Wave Rectifier circuit two diodes are now used, one for each half of the cycle. The full-wave rectifier consists of a center-tapped transformer, which results in equal voltages above and below the center-tap. In full wave rectifier, if we consider a simple sinusoidal a.c voltage, both the negative half cycle or the positive half cycle of the signal is allowed to move past the rectifier circuit with one of the halves flipped to the other halve such that we now have two positive or negatives halves following each other at the output. As in the half-wave rectifier, the rectifier output DC consists of AC components or ripples in it. It is used in soldering iron, Soldering Iron circuit uses Half Wave rectifier and it is also used in mosquito repellent to drive the led. Introduction.
