Patent ID: 7629784

Claim:
A voltage supply arrangement which can be operated in a first or in a second operating mode and is configured to provide a voltage in the first operating mode from a first power range, and from a second power range in the second operating mode, to a first electrical load, the voltage supply arrangement comprising: a voltage converter whose input is coupled to a voltage input of the voltage supply arrangement in order to receive an input voltage and provide a converted voltage at a voltage converter output to a first connection of a first switch; the first switch, which is coupled at a second connection to a voltage output of the voltage supply arrangement, wherein the voltage output is configured for connection of the first electrical load to the voltage supply arrangement; a second switch, which is coupled at a first connection to the voltage input of the voltage supply arrangement and at a second connection to the voltage output of the voltage supply arrangement, wherein the voltage output of the voltage supply arrangement is connected by means of the first switch to the voltage converter output and the voltage output of the voltage supply arrangement is connected by means of the second switch to the voltage input of the voltage supply arrangement; and a drive circuit, which has at least one drive circuit input for supplying at least one control signal, coupled at a first output to a control input of the first switch and at a second output to a control input of the second switch, and is configured to drive the first and the second switch in response to the at least one control signal.
