Firing-angle delay refers to the delay in the firing of a thyristor in a controlled rectifier circuit. The firing angle is the delay between the zero-crossing of the input voltage waveform and the triggering of the thyristor.

The firing-angle delay is directly proportional to the control signal voltage. This means that as the control signal voltage increases, the firing-angle delay also increases. Conversely, as the control signal voltage decreases, the firing-angle delay decreases.

This relationship can be explained by considering the operation of a controlled rectifier circuit. The control signal voltage is used to trigger the thyristor and control the output voltage. When the control signal voltage is low, the thyristor is triggered earlier in each cycle of the input voltage waveform, resulting in a smaller firing angle and a higher average output voltage. On the other hand, when the control signal voltage is high, the thyristor is triggered later in each cycle, resulting in a larger firing angle and a lower average output voltage.

The firing-angle delay is not affected by the synchronizing transformer voltage. The synchronizing transformer is used to ensure proper synchronization between the input and output voltages in a controlled rectifier circuit. It does not directly affect the timing of the thyristor firing.

In conclusion, the firing-angle delay in a controlled rectifier circuit is directly proportional to the control signal voltage, but not affected by the synchronizing transformer voltage.

The firing-angle delay isa)inversely proportional to the synchronizing...
The firing-angle delay refers to the time delay between the application of a control signal to a device, such as a thyristor, and the actual triggering or firing of that device. In the context of thyristors, including Silicon-Controlled Rectifiers (SCRs), the firing angle delay determines the point in the AC waveform at which the device starts conducting.
When it comes to controlling the firing angle of an SCR, the control signal voltage plays a crucial role. The control signal voltage is typically applied to the gate terminal of the SCR. By varying the amplitude or duration of the control signal voltage, the firing angle of the SCR can be adjusted, thereby controlling the amount of power delivered to a load.
In this case, option D states that the firing-angle delay is directly proportional to the control signal voltage. This statement is correct. As the control signal voltage increases, the firing-angle delay decreases, resulting in an earlier trigger and a smaller delay between the control signal and the conduction of the SCR.
