A diode is to electric current like a one-way valve is to water, it allows electric current to flow in only one direction. This property of the diode is very useful in creating simple rectifiers which are used to convert AC to DC. Full-wave rectifiers have some fundamental advantages over their half-wave rectifier counterparts. The average (DC) output voltage is higher than for half-wave rectifier, the output of the full-wave rectifier has much less ripple than that of the half-wave rectifier producing a smoother output waveform. A Bridge rectifier is an Alternating Current (AC) to Direct Current (DC) converter that rectifies mains AC input to DC output. Bridge Rectifiers are widely used in power supplies that provide necessary DC voltage for the electronic components or devices. They can be constructed with four or more diodes or any other controlled solid-state switches
