What is the maximum voltage cutting angle typically allowed?

The maximum voltage cutting angle is typically considered to be 90 degrees because it signifies a complete suppression of the voltage in a controlled environment, particularly in AC systems where the waveform can be manipulated. At this angle, the conduction phase of the cycle is effectively fully interrupted, resulting in the maximum reduction of the output voltage to zero.

This 90-degree cutting angle is significant in applications such as power rectifiers or thyristors, where controlling the triggering angle directly influences the power delivered to a load. A cutting angle of 90 degrees means that no part of the AC waveform is allowed to pass through, which is a crucial aspect of managing power in various electrical systems.

While other angles such as 45, 60, and 75 degrees may be used for specific applications to balance power flow and control, they do not represent the maximal cutting capability. Those angles allow some portion of the waveform to conduct, resulting in a proportionate voltage output rather than a complete shutdown which 90 degrees achieves.
