Center Tapped Full Wave Rectifier Waveform. Do not connect any capacitor across the load. A rectifier circuit whose transformer secondary is tapped to get the desired output voltage using two diodes alternatively to rectify the complete cycle is called as a center tapped full wave rectifier circuit.
When compared to the half wave rectifier both the half cycles are used to produce the corresponding output. The center tapped full wave rectifier is build with a center tapped transformer and two diodes d1 and d2 are connected as shown in below figure. The features of a center tapping transformer are.
Analysis in negative half.
Figure below shows a circuit diagram of the center tapped full wave rectifier. Analysis in positive half cycle. Since a center tapped transformer is used for the rectification purpose this is called center tapped full wave rectifier. This is basically an improvement over half wave rectifier in which output current only flows for the positive half cycle of input supply.
