Why step down transformer is used in full wave rectifier?
Keeping this in consideration, why we use step down transformer in full wave rectifier?
Transformer is a device which reduces or increases the AC voltage. In half wave rectifier, we generally use a step-down transformer because the voltage needed for the diode is very small. Applying a large AC voltage without using transformer will permanently destroy the diode.
Additionally, why do we use step down transformer? It is designed to reduce the voltage from the primary winding to the secondary winding. As a step-down unit, the transformer converts high-voltage, low-current power into low-voltage, high-current power. The larger-gauge wire used in the secondary winding is necessary due to the increase in current.
Just so, what is the role of transformer in full wave rectifier?
The center tapped full wave rectifier uses a center tapped transformer to convert the input AC voltage into output DC voltage. When input AC voltage is applied, the secondary winding of the center tapped transformer divides this input AC voltage into two parts: positive and negative.
Which transformer is used in bridge rectifier?
Working of the Bridge Rectifier Used to Convert 230V AC to 5V DC. Step-down transformers are used to convert 230V AC (high voltage) into 12V AC (low voltage).
