The principle, experimental arrangement and related results of the test electromagnetic railgun are described in this paper. A 50kJ capacitor bank is used as the primary power supply, and an inductor of 2.5μH as the secondary magnetic energy storage. In order to supply a sustained current to the railgun, four switches are inserted in the circuit for adjusting the variation of the current. The barrel is 30cm long and with a cross-sectional area of 0.8×0.6cm2. It is shown from two launching tests that a 0.34 gram...

本文介绍了电磁轨道炮的工作原理,原理性实验装置和实验结果。实验中用贮能50kJ的电容器组作为能源,用一个2.51μH的贮能电感器和四个开关调节电流波形,以便确保持续地向轨道炮供电。炮体长为30cm,炮膛口径为0.8×0.6cm~2。在两发首次进行的实验中,把340mg重的聚碳酸酯弹丸加速到1.5km/s的速度。

The topology and the principle of the three phase four switches power converter main circuit of the switched reluctance motor drive are given. The mathematical model is set up. Compared with the two other types of the three phase power converter main circuit and tested with the prototype, it is shown that it has the higher ratio of the performance to the cost.

给出了三相四管式开关磁阻调速电动机功率变换器主电路拓扑及其工作原理 ,建立了其数学模型 ,通过与其它两种三相功率变换器的比较及样机系统实验 ,结果表明 ,该功率变换器具有较高的性能价格比

In this paper,a three level DC/DC converter is presented.The converter is especially well suited for high input voltage.There is only a half of the input voltage imposes on each of the four switches,because two legs of the converter are connected in series with each other across the dc input source (dc bus). Each switch can realize ZVS with phase shift technique.A theoretical analysis and experimental result are given on 1kW example.The measured maximum efficiency is 95.1%.
