DC-DC CONTROL WITH FREQUENCY-DEPENDENT PHASE CORRECTION IN VOLTAGE FEEDBACK
The invention relates to a method for controlling a DC-to-DC converter (W), wherein the converter (W) converts a voltage (UH) of a first converter side (HS) into a voltage (UL) of a second converter side (LS). A target voltage (US) and an actual voltage (UL) are input to a controller (R). Both relate to the second converter side. Furthermore, an actual voltage (UHF) which relates to the first converter side (HS) is input to the controller (R). The controller is operated according to a control target which provides the minimisation of the difference between the target voltage (US) and the actual voltage (UL) of the second converter side (LS). The actual voltage (UHF) of the first converter side (HS) is provided by transmitting the voltage (UH) applied to the first converter side (UH) via a filter (F). The transmission function of the filter (F) provides a phase increase for a predefined frequency range to be suppressed in order to at least partially compensate for the dynamics that decrease with increasing frequency. As a result, the transmission of interferences in said frequency range can be damped by means of the converter. The invention also relates to a corresponding vehicle DC-to-DC converter, to a corresponding DC-to-DC voltage converter control device and to a corresponding computer program.
