摘要
轨道炮的发射需要幅值足够大脉宽足够宽的梯形波电流。研究了两个电感型脉冲电源模块给同一负载供电时的三种工作模式,在不同的工作模式下,负载的电流放大倍数和脉宽增值不同。由实验和仿真结果知:两个STRETCH meat grinder电源模块在相同模式下工作时,负载电流放大倍数最大,脉宽增值最小。在主管同开同断且晶闸管延时的模式下工作时,脉宽增值最大,电流放大倍数最小。以第二模块延时第一模块的模式工作时,负载电流的放大倍数和脉宽增值都是居三模式之中,因此可通过选取合适的触发方式获得所需要的负载电流。
The launching of the railgun needs enough amplitude and width trapezoid wave current.This article presents three working modes of two inductive pulsed power supplies supplying one load.The load current magnification and the pulse width increment are different under these three different working modes.Simulation and experiment results show:the load current magnification is the largest and the pulse width increment is the smallest when two STRETCH meat grinder modules work at the same mode;the load current magnification is the smallest and the pulse width increment is the largest when the main switches of two STRETCH meat grinder modules open simultaneously and the thyristor of the second model delays the first one;the load current magnification and the pulse width increment is medium when the second model delays the first model. From the results we can get the right current by choosing the appropriate triggering.
