Abstract

This article describes a method for optimizing the distribution of capacitances of a voltage multiplier. This action is necessary to reduce the weight of the device without reducing the output power at the load. The simulation was carried out for the case of an input voltage of 950 V, an output voltage of 10 kV, a frequency of 750 kHz, and a capacitance range from 1 to 25 nF. A comparison was made for constant and variable capacity. It is shown that using the dependence of capacitance on capacitor number allows for reducing mass of the device by 7% compared with a constant distribution. The main elements of a voltage multiplier are diodes and capacitors. A diode and a capacitor connected in parallel form a stage that increases the voltage amplitude. A pair of series connected steps form a cascade. In addition to increasing the output voltage, the first stage cuts off the negative components of a signal, and the second one cuts off the positive one.
