Full-wave rectifiers using a center-tapped transformer and a bridge rectifier
When AC voltage is applied to a rectifier circuit, it converts the alternating current into direct current. There are different types of rectifier circuits, including full-wave rectifiers. In this question, we are considering two types of full-wave rectifiers: one that uses a center-tapped transformer and another that uses a bridge rectifier.
1. Center-tapped transformer full-wave rectifier
A center-tapped transformer is a type of transformer that has a center tap on the secondary winding. This center tap provides two equal voltage outputs that are out of phase with each other. The rectifier circuit using a center-tapped transformer consists of diodes connected to the secondary winding of the transformer. These diodes allow the current to flow in only one direction.
2. Bridge rectifier
A bridge rectifier is another type of full-wave rectifier that does not require a center-tapped transformer. It consists of four diodes connected in a bridge configuration. The AC input voltage is connected to the bridge rectifier, and the output is obtained across the load resistor.
Frequency of outputs
In both the center-tapped transformer full-wave rectifier and the bridge rectifier, the output frequency is twice the input frequency. This is because in both cases, each diode conducts during both the positive and negative half cycles of the input AC voltage.
In the center-tapped transformer full-wave rectifier, during the positive half cycle of the input voltage, the current flows through one diode, and during the negative half cycle, the current flows through the other diode. This results in two output pulses per input cycle, effectively doubling the frequency.
Similarly, in the bridge rectifier, during the positive half cycle of the input voltage, the current flows through two diodes, and during the negative half cycle, the current flows through the other two diodes. Again, this results in two output pulses per input cycle, doubling the frequency.
Therefore, the frequencies of the outputs in both the center-tapped transformer full-wave rectifier and the bridge rectifier are 100 Hz each, considering the input frequency of 50 Hz.
Hence, the correct answer is option 'A': 100 Hz each.
