Abstract
A voltage converter, for converting an input voltage (U.sub.i) to an output voltage (U.sub.0), includes a plurality of cascaded voltage multipliers (VM1-VMN) having clock inputs, a control circuit (CNTRLG) for supplying clock signals to the clock inputs, for controlling the voltage multipliers (VM1-VMN). The control circuit (CNTRLG) includes circuitry (SL) for activating selected ones from the plurality of the voltage multipliers (VM1-VMN). The clock signals can be programmed to a part of the voltage multiplier to a non-active state. The voltage converter can, in addition, be provided with monitoring circuitry (MN) coupled between the output of the voltage converter and an input of the circuitry (SL). The monitoring means (MN) measures the output voltage (U.sub.0) in order to take a decision about the required number N of active voltage multipliers (VM1-VMN).
