Regulating device for a multi-phase voltage converter

A regulating device coupled to a multi-phase voltage converter, comprising:

• a connecting element for picking-off input or output voltage signal at a terminal of the multi-phase voltage converter, wherein the input or output voltage signal is characterized by a voltage ripple resulting from current measurement errors within the multiphase voltage converter;
• a filter, coupled to the connecting element such that the connecting element is connected between the filter and the multi-phase voltage converter, and wherein the filter is configured to receive the input or output voltage signal and, in response, the filter is further configured to provide a filter output signal based on a frequency and an amplitude of the voltage ripple;
• and
• a correcting unit, coupled between the filter and the multi-phase voltage converter, wherein the filter is connected between the connecting element and the correcting unit, and wherein the correcting unit is configured to receive the filter output signal and, in response, the correcting unit is further configured to provide an actuating signal to the multi-phase voltage converter, and in response to the actuating signal, the multi-phase voltage converter is configured to compensate for said current measurement errors by optimizing or minimizing the voltage ripple of the input or output voltage signal.
