200 Hz
Bridge Rectifier Output Frequency Explained
A bridge rectifier is a type of full-wave rectifier circuit. Its main function is to convert alternating current (AC) into pulsating direct current (DC).
In an AC waveform, there are both positive and negative half-cycles. A full-wave rectifier, like the bridge rectifier, works by inverting the negative half-cycles and combining them with the positive half-cycles to produce a unidirectional current flow.
Because both the positive and negative halves of the input AC waveform are utilized and converted into pulses of the same polarity in the output, the output waveform has two pulses for every complete cycle of the input AC waveform.
This characteristic means that the frequency of the output waveform is double the frequency of the input waveform.
The relationship can be expressed as:
\( \text{Output Frequency} = 2 \times \text{Input Frequency} \)
Given the input frequency of the bridge rectifier is 100 Hz.
Using the formula:
\( \text{Output Frequency} = 2 \times 100 \text{ Hz} \)
\( \text{Output Frequency} = 200 \text{ Hz} \)
Therefore, if the input frequency of a bridge rectifier is 100 Hz, the output frequency will be 200 Hz.
