What is the voltage ripple in a 3-phase 6-pulse x-ray system?

In a 3-phase 6-pulse x-ray system, the voltage ripple is determined by the configuration of the rectification and the nature of the power supply. For 3-phase systems, the ripple is generally lower than that of single-phase systems due to the way the phases work together, resulting in a more consistent output.

A 3-phase system effectively combines three alternating currents, meaning that the output voltage remains more stable than in a single-phase setup. The 6-pulse rectification process, which utilizes diodes to convert the AC to DC, contributes to reducing ripple by effectively "smoothing" out the pulsations in the output voltage.

The typical voltage ripple for a 3-phase 6-pulse system is commonly calculated or referenced to be around 14%. This is attributed to the properties of ripple in relation to the number of phases and the pulse configuration. The 14% figure reflects the balance between maintaining an efficient level of rectification while minimizing the variations in output voltage, which is crucial for the proper functioning of x-ray equipment.

Thus, in this context, the answer correctly identifies the voltage ripple as 14%, which is a standard expectation for this type of x-ray system setup.
