Rectifier Circuit Using Center Tapped Transformer

- April 27, 2018

The input voltage is coupled through the transformer to the center tapped secondary. A rectifier is said to be center tapped if it can rectify both the positive and the negative halves of the cycle.

Center Tapped Full Wave Rectifier Electrical Concepts

The centre tap is usually considered as the ground point or the zero voltage reference point.

Rectifier circuit using center tapped transformer. The center tapped full wave rectifier uses a center tapped transformer to convert the input ac voltage into output dc voltage. For full wave rectification we have use two p n junction diodes d 1 and d 2. By using a transformer with a presence of wire at the secondary winding it makes the transformer center tapped.

Full wave rectifier center tapped transformer figure 1 gives the basic circuit of a full wave rectifier center tapped transformer driven from a ac. Rectifiers using a center tapped transformer are an improvement on half wave devices. A center tapped rectifier is a type of full wave rectifier that uses two diodes connected to the secondary of a center tapped transformer as shown in figure a.

It converts the ac input voltage into dc voltage the two diode d 1 and d 2 are connected in the circuit as shown in the circuit diagram below. This is the reason it is termed as a center tapped full wave rectifier. They are easier to filter because of the higher output frequency.

When input ac voltage is applied the secondary winding of the center tapped transformer divides this input ac voltage into two parts. Mains and using resistive load with no filter. Center tapped full wave rectifier bridge rectifier using four diodes if two branches of a circuit is connected by a third branch to form a loop then the network is called a bridge circuit out of these two the preferable type is bridge rectifier circuit using four diodes because the two diode type requires a center tapped transformer and not reliable when compared to bridge type.

This video how to build ac to dc full wave rectifier using a center tapped transformer and using two capacitors acts as the filter. Input voltage12v 0 12v converts into the pure dc output voltage. In the case of centre tap full wave rectifier only two diodes are used and are connected to the opposite ends of a centre tapped secondary transformer as shown in the figure below.

The center tapped full wave rectifier employs a transformer with the secondary winding ab tapped at the centre point c. The output winding of the power transformer is center tapped. However the center tap also cuts the.
