A Marx generator with a doubled output voltage

A generator of high-voltage pulses with doubling of the output voltage built according to the Marx scheme on the basis of ten stages connected in series is described. IGBT transistors are used as switches in the circuit. A specific feature of the generator circuit design is the substitution of charging diodes for charging resistors and connection of the supplying voltage through an inductor. This made it possible to double the amplitude of pulses across a load, which is proportional to the number of connected stages, and minimize the power loss during charging of storage capacitors. In an experiment performed at a supply voltage of 500 V, a pulse voltage of 7.4 kV was obtained across a load of 400 Ω.
