Question
Download Solution PDFTransformer utilization factor of a half wave rectifier is equal to __________.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFTransformer Utilization Factor (TUF) of a half-wave rectifier is 0.287.
Transformer Utilization Factor is defined as the ratio of the DC power output and the AC rating of the transformer's secondary coil. This factor indicates the effectiveness of a transformer in a circuit.
For a half-wave rectifier, the TUF is particularly low because the rectifier circuit is only using half of the AC cycle. As such, the transformer isn't fully utilized since power is not drawn during the entire cycle.
In the case of a half-wave rectifier, the maximum value of the transformer utilization factor is 0.287 or 28.7%. This low value indicates that the rectifier only utilizes approximately 28.7% of the transformer's capabilities, leaving a large amount of potential wasted. This is one of the reasons half-wave rectifiers are less common in practical applications than full-wave rectifiers, which feature a higher TUF.
So, among the given options, option 2 (0.287) is the correct answer.
