NANOSECOND PULSE GENERATOR Russian patent published in 2021 - IPC H03K3/53 

FIELD: high-voltage pulse technology.

SUBSTANCE: invention relates to high-voltage pulse technology. The device contains an active switch connected in parallel to the charger, a drift diode with an abrupt recovery of the non-conducting state, a load, as well as first and second resonant circuits, each of which includes capacitive and inductive energy storage, respectively, of the first and second circuits. The second resonant circuit additionally contains a constant voltage source connected in series to the inductive energy storage of the second circuit and connected in parallel to the capacitive energy storage of the second circuit. Moreover, the capacity of the latter is 10-20 times greater than the capacity of the capacitive energy storage of the first circuit to ensure a linear acceleration of the current through the inductive energy storage of the second circuit. In this case, the voltage of the constant voltage source U_source is 10-40% of the voltage of the charger U_charge , inductive energy storage devices of both the first and second circuits are connected in series to a drift diode, which is configured to break the reverse current at the time when the total charge Q_diode passed through it is determined by the expression Q_diode = ∫Idiode * dt = 0, where t is the operating cycle time of the drift diode from 0 to t₃; Q_diode - charge passed through the drift diode; I_diode - current through the drift diode; t₃ is the moment of breakage of the reverse current through the drift diode. Moreover, a constant voltage source, a capacitive energy storage of the second circuit and a drift diode are connected to a common bus at the second output.

EFFECT: technical result of the proposed solution is to increase the repetition rate of the output pulses due to the absence of residual currents in the drift diode with a sharp recovery of the non-conducting state after the end of the operating cycle.
