  • Patent number: 7579713
    Abstract: 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 (S1) for a controllable discharging of the energy stored in the inductive energy storage element (L), each second switching circuit (S1) 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 1) comprising a parasitic element; control voltage selection means for selectively supplying a control voltage to the parasitic element of the switching circuits (S1) such that a current flow trough the parasitic element of the respective switching circuit (1) is inhibited when the second switching circuit (S1) is turned off. A negative influence of parasitic elements (e.g.

  • Publication number: 20070030617
    Abstract: A voltage converter comprises an inductive circuit (L) for storing energy during an inductive magnetizing mode and transferring energy during an inductive demagnetizing mode. In addition the voltage converter comprises at least two non-inverting branches (12,13,14) for providing at least two non-inverted output voltages (Va,Vb,Vc) and an inverting branch (15) for providing an inverted output voltage. The inverting (15) and non-inverting (12,13,14) branches being parallely coupled to an output (10) of the inductive circuit (L). The inductive circuit being arranged to transfer energy to the inverting branch (15) and to one of the at least two non-inverting branches (12,13,14). Through this, the inverted voltage (Vinv) and the corresponding non-inverted output voltage (Va,Vb,Vc) of the one of the at least two non-inverting branches (12,13,14) are having an opposite polarity and a substantially equal magnitude.
