High-voltage transformer and power supply for an x-ray tube including such a transformer

A high-voltage transformer, comprising:

• a plurality of elementary transformers, in which each elementary transformer comprises:
• an elementary primary circuit configured to be powered by an elementary primary voltage;
• an elementary secondary circuit that comprises:
• at least one secondary winding;
• and
• at least one capacitor, each connected to the terminals of a secondary winding, so as to balance the secondary voltages, with one another;
• wherein the elementary secondary circuit is configured to generate an elementary balanced secondary voltage;
• and
• an elementary magnetic circuit configured to couple the elementary primary circuit and the elementary secondary circuit;
• wherein the output voltage of the transformer is equal to the sum of the elementary balanced secondary voltages, and wherein the elementary primary circuits are connected to one another so as to form a common circuit with the elementary transformers, wherein said common circuit is configured to be supplied by a primary voltage, which primary voltage is equal to the sum of the elementary primary voltages.
