The invention relates to a Graëtz bridge converter rectifier, wherein at least one rectifier arm, located between a single AC terminal and a single DC terminal, comprises multiple unidirectional electronic components (5), connected in parallel, connected on one side to the DC terminal by means of a conductive assembly, referred to as the component assembly, and on another side to the AC terminal. The invention is characterized in that for at least one rectifier arm, the component assembly comprises a plurality of separate component bars (9A, 9B) each having at least one end connected to the DC terminal, the unidirectional components (5) being distributed between the component bars (9A, 9B) in as many parallel-connected component assemblies (71, 72) as there are component bars (9A, 9B).
