Abstract

A multiphase DC voltage converter and a method for controlling a multiphase DC voltage converter, having at least two parallel coils which are controlled in a time-shifted manner, at least one control unit for activating the coils, and at least one magnetically sensitive sensor element for detecting a magnetic field generated by the current flow through the coils. The control unit controls the current flow through the coils as a function of an output signal of the at least one sensor element.
