    Abstract: The invention relates to a method for controlling a rectifier circuit and to a corresponding rectifier circuit. Said rectifier circuit has a rectifier (2) in series with an inductor (4), a diode (5) and a load (6). A capacitor (7) is arranged parallel to the load (6) and a controlled switch (8) is arranged parallel to the series connection of the diode (5) and load (6). Said switch is connected to a control device (9) which produces a control signal using the voltage (U3) through the load. The aim of the invention is to improved the efficiency. The control device (9) has a phase displacement device (12) which effects a phase displacement of the alternating component of the voltage (U3) through the load in the order of magnitude of 270 degrees. This allows the direct voltage signal that is used for obtaining a control signal for the switch (8) to be superposed by an alternating voltage signal whose frequency corresponds to the frequency of the ripple at the output of the rectifier (2) and which has a phase difference in relation to the ripple that is less than a predetermined measure.
