Abstract

Abstract

Based on the practical needs of the simulated hail impact test of photovoltaic panels, a matching study between the reluctance coil launcher and the pulse power supply was carried out. The applicability of the two basic pulse discharge circuits, the current-continuing front type and the current-continuing back type, is theoretically analysed, and the results show that the current-continuing front type pulse discharge circuit has better matching with the launcher. In view of the reverse braking problem of the residual pulse current during the launching process, an energy-discharge circuit that can quickly consume the residual pulse current is designed to improve the topology of the current-continuing front type pulse discharge circuit to further improve its applicability, and it is verified with the help of simulation. The results show that the energy-discharge circuit can quickly consume the reverse pulling force effect of the residual pulse current, and the launch performance of thrown body is significantly improved, the exit speed of the thrown body is 50.8% higher than that of traditional discharge circuits, and the system emission efficiency is increased by 127.5%. This study can provide reference for the application of the reluctance coil launch technology in the field of simulated impact test.
