A circuit method for steepening the rising edge of square wave pulse

In order to solve the problem of slowing down the pulse rising edge due to the lead inductance at the output of the pulse generator, a circuit structure that can steepen the pulse rising edge is proposed in this paper. The steepening circuit consists of a low voltage DC power supply, resistors, diodes and capacitors. It is connected in parallel to the load terminals. The steepening circuit uses the reverse recovery process of the diode to steepen the pulse rising edge. Firstly, the working principle of the steepening circuit and the influencing factors of the steepening effect were simulated and analysed. Subsequently, a pulse rising edge steepening device was further developed. Finally, a Marx pulse generator with an output voltage of 3 kV, a pulse width of 500 ns, and a pulse rising edge of 80 ns was used to test the performance of the designed pulse rising edge steepening device. The experimental results show that the effect of the pulse rising edge steepening device is obvious, and the best effect can reduce the pulse rising edge of the pulse by 36 ns. At the same time, this paper also gives the regulation law of the steepening effect through experimental analysis.
