Abstract

A voltage multiplier 10 comprises a series of multiplier stages 12a, 12b, 12c, 12d. Each multiplier stage, for example 12b, comprises a first input 16b, a second input 14b, a first output 16c and second output 14c. The first and second outputs of a preceding multiplier stage are interconnected with first and second inputs of a subsequent multiplier stage. Furthermore, each multiplier stages, for example 12b, comprises two series connected diode elements D5, D6 having the same current conducting direction. The two series connected diode elements D5, D6 interconnect the first input 16b and the first output 16c. The second output 14c is coupled between the two series connected diode elements D5, D6. Each multiplier stage, for example 12b, comprises a buffer capacitor C6 interconnecting the respective first input 16b and the respective first output 16c. At least some multiplier stages, for example 12b, comprise a push-pull capacitor C4 interconnecting the respective second input 14b and the respective second output 14c. The first input 16a of a first multiplier stage 12a and the first output 16e of a last multiplier stage 12d provide outputs for a load 42. The second input 14a of the f…
