A key problem in providing more affordable health care with sufficient quality is in the field of X-ray computed tomography. The provision of high-voltage precision power supplies is of utmost importance to solving this task. The current paper evaluates the previous work done in this field and proposes a model for evaluating possible system designs. The presented study solved some of the problems that arose when studying the operation of a voltage multiplier. Choosing the number of the multiplier cells were taken into account weight and size, and current-voltage characteristics of capacitors and diodes.
