A driver circuit to adjust the pulse edges of Marx generators
A novel driving circuit for the adjustment of pulse edges in Marx generators is proposed. By adjusting the driving voltage amplitudes of the charge and discharge switches, the Miller plateau time is controlled in the driving circuit. Then the turn-on speed of the switches and the pulse edges of high-voltage pulses are adjusted. This drive circuit is simple in structure and does not require additional independent signals. A model is established to study the relationship between the driving voltage amplitudes and the turn-on speed of switches. Combined with the theoretical analysis results, the parameters of the driving circuit are designed, and the simulation results show that the driving circuit can adjust the pulse edge. A solid-state Marx generator with the proposed driving circuit was built to experiment under capacitive load and resistive load. Using this method, the edge adjustment of 3.6 kV output pulse from 55 ns to 7.7 μs for 6-stage Marx circuit was achieved, and the influence of different resistive loads on the pulse edge is compared and analyzed. The experiment results show that the driving circuit has unique advantages in improving the edge adjustment performance of pulsed generators.
