Abstract
In a voltage supply wherein a voltage multiplier produces an output voltage level in proportion to its driving frequency, the output voltage level is regulated by incorporating a voltage controlled oscillator to vary the driving frequency in accordance with the output voltage level of the voltage multiplier. To improve operating efficiency, current amplifiers are disposed between the output of the voltage control oscillator and the input of the voltage multiplier. Furthermore, a level shift means is incorporated in another embodiment for disabling the voltage controlled oscillator and for impressing a rail voltage level at the output terminal of the voltage multiplier.
