The invention relates to an voltage converter for converting a voltage to multiple output voltages, comprising a first switching circuit (SO) connected to an inductive energy storage element (L) for allowing and interrupting a current flow through the inductive energy storage element (L); at least two second switching circuits (S) for a controllable discharging of the energy stored in the inductive energy storage element (L), each second switching circuit (S) being connected to the inductive energy storage element (L) in parallel connection to each other at its respective input and each second switching circuit (S) comprising a parasitic element; control voltage selection means for selectively supplying a control voltage to the parasitic element of the switching circuits (S) such that a current flow trough the parasitic element of the respective switching circuit () is inhibited when the second switching circuit (S) is turned off. A negative influence of parasitic elements (e.g. diodes) can be suppressed by a suitable selective control of the bulk voltage.
