Abstract:
1. A voltage converter comprising: an inductive circuit for storing energy during an inductive magnetizing mode and transferring energy during an inductive de-magnetizing mode; at least two non-inverting branches for providing at least two non-inverted output voltages and an inverting branch for providing an inverted output voltage; the inverting and non-inverting branches being parallely coupled to an output of the inductive circuit the inductive circuit being arranged to transfer energy to the inverting branch and to one of the at least two non-inverting branches that is activated, wherein the inverted voltage and the corresponding non-inverted output voltage of the one of the at least two non-inverting branches have an opposite polarity and a substantially equal magnitude; and wherein said magnitude is determined by the selection of the one non-inverting branch that is activated.
