Detailed Solution
Download Solution PDFThe correct answer is: 1) The transformer utilization factor (TUF) is equal for both the bridge and center-tapped rectifier.
Explanation:
Transformer Utilization Factor (TUF)
TUF measures how effectively a transformer's secondary winding is used in a rectifier.
| Rectifier Type | Typical TUF Value | Key Characteristics |
|---|---|---|
| Bridge Rectifier | ~0.812 | Uses entire secondary winding continuously. Higher efficiency. |
| Center-Tapped | ~0.693 | Only half the secondary winding is used at a time. Lower efficiency. |
| Half-Wave | ~0.287 | Utilizes transformer poorly (only half-cycle). |
