Abstract: Nanosecond pulse electric field ablation requires the generation of thousands of volts of nanosecond pulses on a 100 Ω load, and accelerating the pulse front is beneficial for obtaining narrower nanosecond pulses. This article proposes a solid-state Marx generator with a fast front, which inserts an inductor into each stage of the circuit and allows the discharge tube and charging tube to conduct simultaneously for tens of nanoseconds. After the discharge tube is fully opened, the charging tube is turned off to discharge the load, eliminating the limitation of stray inductance on the pulse front by the discharge tube and discharge circuit, and obtaining a high-voltage pulse with a fast front. A 32 level Marx prototype was built, and in the experiment, a high-voltage pulse with a voltage rise of 35 ns, a pulse width of 800 ns, and a current of 186 A was obtained on a low resistance load of 100 Ω by adjusting the through time. We compared and analyzed the effect of the direct time between the charging tube and the discharge tube on the rising edge, and found that the longer the direct time, the faster the front of the pulse current. The maximum peak current at the output end can reach 186 A. This indicates that the pulse voltage source can effectively increase the current output and improve the system’s load capacity. Compared with traditional improvement methods, this scheme not only improves the system’s anti-interference ability, but also reduces the number of switches used and reduces the cost of pulse power supply.
