  • Output voltage U 2 is always greater or at least equal to the input voltage Ui.
  • the up-converter 1 comprises an inductor 2 connected between input and output and a switch 4 by means of which the inductance 2 can be switched alternately against the reference potential (ground) or the output.
  • the switch 4 When the switch 4 is closed, energy is stored in the inductance 2, which is additionally output to the output when the switch 4 opens again. At the output can therefore higher Output voltages U 2 are generated as the input voltage Ui.

  • Such up-converters 1 are u. a. used to protect safety-relevant consumers in vehicles against undervoltage.
  • the use of such up-converters in motor vehicles is problematic because of the high currents and powers.
  • the high currents require in particular the use of large and heavy components that can not be automatically populated on a printed circuit board.
  • overheating of individual components or solder joints can occur because the entire current flow concentrates on a path or a component.
  • An essential aspect of the invention is to use a polyphase, clocked voltage converter for certain applications in a motor vehicle instead of a single-phase converter.
  • a multiphase voltage converter basically consists of a plurality of single-phase voltage converters connected in parallel, each comprising an inductance, a transistor for charging the inductance, and a switch connected between inductance and converter output.
  • the use of a multi-phase, clocked voltage converter thus has the advantage that the total current is distributed uniformly over n phases and thus a correspondingly lower current flows in each phase.
  • the components contained in the individual phases can thus be made smaller and less expensive.
  • the power loss in the individual components decreases, which reduces the thermal load. Additional cooling measures may therefore no longer be necessary.
  • Another advantage is the reduced EMC emission of the EMC filters connected to the input and output. With a correspondingly high number of phases, electrolytic capacitors may possibly be replaced by MLCC.
