Q. Which type of transformer is required to create a 180 degree input to a rectifier?
Solution:
- Center-tapped secondary is used to create a 180 degree input to a rectifier.
- 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.
- A center tapped full wave rectifier is a rectifier which uses a center tapped transformer to convert the complete AC signal into DC signal. The main advantage of a center tapped full wave rectifier is that it allows electric current during both positive and negative half cycles of the input AC signal.
