Abstract
Abstract A circuit configuration and a method for supplying voltages to an electrically functional unit that has a central voltage source UC and a plurality of circuit elements. Between the central voltage source and the circuit elements, a device assigned to the circuit elements is connected. The device converts the supply voltage, delivered from the central voltage source for the respective circuit elements into a voltage individualized for the circuit elements, and optionally for the circuit element state, and delivers the converted voltage to the circuit elements.
