Generator of powerful nanosecond pulses (variants)

A generator of high-power nanosecond pulses comprising:

• at least one inductive energy storage device connected in series and a superfast drift step recovery diode, as well as a load connected in parallel to the drift step recovery diode and switches, characterized in that the switches are arranged in series, an inductive energy storage device with the possibility of adjusting the pulse amplitude of the load circuit by varying the time and opening switch, the moment the second switch circuit presented in the time interval between the opening of the first switch and the instant of change of the polarity of the current through the inductive storage device, and the time of its opening is in the time interval from the beginning of the pulse formation on the load to the moment of the next closing of the first switch, two constant voltage sources of the same polarity are inputted, wherein one of them is connected to the first switch and a second source with a smaller amplitude than the first source is connected to the drift diode, whereby the second switch is connected to the common bus and the load is connected to the diode through the drift spacer diode.
