A New DC Source for Experimental Use

In some experimental setups, it is required to obtain ultrahigh direct current voltages, including pulses of a given polarity and energy. Getting direct current for their testing and operation is accompanied by the process of rectifying the alternating current at the output of the power supply, which always requires diodes with a voltage rating higher than the nominal one. At the same time, the allowable voltage limit of the diodes is limited, not more than 10 kV. This article proposes a new design of a power supply with an output capacitance, which makes it possible to charge this capacitor without using diodes on the high voltage side, which significantly increases the reliability of operation and reduces the cost of the design as a whole. Also, the advantages include lower dimensions, and the possibility of obtaining high currents in installations with superconductivity.
