Abstract —A generator of powerful quasi-rectangular high-voltage pulses based on an N -section adder was created from segments of coaxial lines with a common insulating magnetic circuit. For a matched load, the adder provides an N -fold increase in the voltage amplitude relative to the amplitude of the input pulses with the rise and fall times of the output pulses determined by the relations: 2( N – 1)τ s + τ RT , 2( N – 1)τ s + τ FT , respectively, where τ s is the electric length of the adder section, τ RT is the duration of the front of the input pulse, τ FT is the duration of the decline of the input pulse, and N is number of sections. The design and the test results of a 22‑section pulse generator with a 50-Ω matched load are presented. It has the ability to control the voltage of the output pulses in the range of 1–21 kV, a duration in the range of 100–500 ns, and a pulse repetition rate up to 1 kHz, with a front; the drop in output pulses (at the level of 0.1–0.9) is 100 ns.
