A generator of high-voltage quasisquare pulses with relatively uniform tops is described that is based on a voltage-pulse generator and a correcting network. Formulas for the generator components are given. A method for peaking of pulse leading edges by means of a resistance is examined. Pulses with durations of from 0.2 to 2 ..mu..sec, amplitudes to 180 kV, and top nonuniformities of less than or equal to 1.5% were produced experimentally with loads of from 100 to 750 Omega.
