Transistor Generators of High-Power Rectangular Pulses with Submicrosecond Duration

The results of comparative studies of generators of high-power submicrosecond rectangular pulses are presented. The switch in these generators is made in the form of a transistor block with a transformer control circuit. A block consisting of ten transistors connected in series is described, which is able to commutate into a load of 150 Ω rectangular current pulses with an amplitude of 50 A, a duration of up to 1 μs, and rise and fall times of less than 50 ns at a repetition rate of 2 kHz. The possibility of increasing the switched power by increasing the power voltage up to tens of kilovolts is determined.
