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

The invention relates to a high-voltage transformer including: a plurality of elementary transformers (T i ). Each elementary transformer (T i ) includes: an elementary primary circuit (11) intended to be powered by an elementary primary voltage (V1 i ); an elementary secondary circuit (20) including: at least one secondary winding (22 1 , 22 2 ); at least one capacitor (C'), each connected to the terminals of a secondary winding (22 1 , 22 2 ) so as to balance the secondary voltages (V21 i , V22 i ) with one another; in which the elementary secondary circuit (20) is intended to generate an elementary balanced secondary voltage (V20 i ); an elementary magnetic circuit (10) intended to couple the elementary primary circuit (11) and the elementary secondary circuit (20); in which the output voltage (V) of the transformer is equal to the sum of the elementary balanced secondary voltages (V20 i ), and the elementary primary circuits (11) are connected to one another so as to form a common circuit (100) with the elementary transformers (T i ), in which said common circuit (100) is intended to be supplied by a primary voltage (V1), which primary voltage (V1) is equal to the sum of the elementary primary voltages (V1 i ).
