| 1. | Different makes of selsyns, used in interlock systems, have different output voltages.
|
| 2. | The amplification factor is 21-output voltage amplitude divided by input voltage amplitude.
|
| 3. | IN, then the output voltage will be less than the input voltage.
|
| 4. | Now the op-amp increases its output voltage to compensate for the drop.
|
| 5. | Cutoff clamping reduces the output voltage swing but makes the transition faster.
|
| 6. | This is possible due the active control of the AC output voltage.
|
| 7. | IN, then the output voltage will be greater than the input voltage.
|
| 8. | This is the output voltage of R 1 C 1 integrating circuit.
|
| 9. | Thus, the output voltage is brought back up to its original value.
|
| 10. | As a result, its input voltage does not affect the output voltage.
