Full Wave Rectifier Circuit  Full wave rectifier circuit, Current full per cycle A full wave rectifier circuit rectifies the AC in both directions providing a DC signal for each AC cycle. Bridge Rectifier Circuit schematic using 4 diodes labeled CR1 to CR4. Filtering is normally done [not shown] by one or more capacitors attached across the Load. Common diodes used in this application are the 1N4004 diode, 400 volts in a DO-41 leaded package [General Purpose Rectifiers], However there are devices that contain all four diodes in the same package. Bridge Rectifiers contain all four diodes in a four pin package, there are a number of package styles and voltage/current options.  Same full wave rectifier circuit as above showing the input and output waveforms. If the transformer has a center tap, only two diodes are required, Rectifier Terms shows a schematic using a center tapped transformer.
