Abstract An underwater pulse discharge system was designed based on the principle of reversely switched dynistor. It was put forward that the main voltage was not blocked without using magnetic switch, which increased the rise rate of main current. The experimental parameters were determined and discharge experiments were carried out in paper. We can see in experiment that the load is equivalent to a small resistance, and there is a time delay in breakdown process. Breakdown time of the load is about 25μs; the peak precharge current is 397A and the pulse width was 3μs; the peak current of load was 6.5kA, pulse width was 5μs, di/dt was 3.2kA/μs under the main voltage of 12kV and the precharge voltage of 4kV.

Key words： pulse power load discharge under water reverse charge
