Output Characteristics of Helical Magnetic Flux Compression Generators with Varing Current Density Flowing through Coil

코일에 흐르는 전류밀도를 변화시킨 자장압축전기의 출력특성

We designed and manufactured helical magnetic flux compression generator, in which, the current density was reduced by increasing the number of wires by stages, and the voltage between wires was reduced by decreasing the time rate of inductance change. The figure of merit and the energy multiplication ratio of the generator were measured as a function of current density flowing through coil and their characteristics were analyzed. When the current density of coil was more than 250 kA/cm, the figure of merit and the energy multiplication ratio were decreased rapidly.
