Design and simulation of a simulated hail launcher based on pulsed power technology

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 matching between the current-continuing front type pulse discharge circuit and the launching is superior. In view of the reverse braking problem of the residual pulse current during the launching process, an energy-discharge circuit that can quickly consumed 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, and the results show that the energy-discharge circuit can quickly consumed the effect of the residual pulse current, and the exit speed of the thrown body is significantly improved. This study is a meaningful attempt to apply the pulsed power technology in the field of simulated impact test.
