Questions and Answers

What is the main advantage of using an autotransformer in an x-ray imaging system?

It operates solely on direct current.

It integrates multiple winding systems.

It simplifies voltage control at high levels.

It enables low voltage to be easily stepped up. (correct)

How does the autotransformer differ from a conventional transformer?

It operates independently of electromagnetic principles.

It has multiple cores for efficiency.

It can only step down voltage.

It has only one winding with multiple connections. (correct)

Which statement correctly describes the voltage relationship in an autotransformer?

Both primary and secondary voltages are equal.

Secondary voltage is controlled entirely outside the autotransformer.

Secondary voltage is always lower than primary voltage.

Secondary voltage is directly related to the number of turns enclosed by the connections. (correct)

Study Notes

X-ray Imaging System Power Supply

Power for x-ray imaging initially goes to an autotransformer.
The voltage from the autotransformer to the high-voltage transformer is adjustable and controlled.
Controlling a lower voltage and then increasing it is safer and easier than directly controlling a high kilovolt level.

Autotransformer Operation

Autotransformer operates on electromagnetic induction.
It differs from conventional transformers.
It has one winding and one core.
The winding has multiple connections.
Two connections (A and A′) receive input power; these are primary connections.
The autotransformer can increase the voltage to roughly double the input voltage.

Autotransformer Voltage Relationship

The voltage output is directly related to the number of turns enclosed by the connections (primary and secondary).
The autotransformer follows the same voltage ratio law as a conventional transformer.
