Zusammenfassung:	PROBLEM TO BE SOLVED: To generate only slight amount of current harmonics with the inductance required between the power source and a rectifier input side and to, at the same time, control an intermediate circuit voltage by performing the switching connection of a capacitor with a voltage adjustment device while relying on the output voltage of the rectifier. SOLUTION: The output side of a three-phase rectifier circuit is connected to a capacitive load 2, and an input side is, by way of an inductance 3 assigned on three lines, connected to power source 4. In order for compensate an reactive power, star-connected capacitors 5 are provided on the input side of a rectifier. The capacitors 5 and permitted for individual connection switching and shut-off switching, through an switching device 6. The switching device 6 is controlled by a voltage adjustment device 7 for the output voltage of the rectifier. The three-phase rectifier circuit 1 is, for example, suitable for the user with high frequency X-ray generator.
