摘　　要：本文主要阐述了一种功率脉冲驱动方法、功率脉冲发生装置技术实施方法以及空间取电技术的研究。具体为采用双极板电场感应取电的方式从高压输电线路上获取电压,通过在高压线路和大地之间架设两个平行于大地的极板构成一个电容,高压线与大地之间的高压电场将使此电容的两极之间产生电压差,作为功率脉冲驱动电压。将交流电压通过整流转化成直流电,对直流进行电能存储,输出直流,并通过控制模块产生使三极管导通、关断的控制信号,从而将输出的直流电转化成功率脉冲信号,并将三极管控制在发生二次击穿但可逆的范围内,最后根据输出的脉冲信号驱动负载。This paper proposes a method of power pulse drive、power pulse generator technology implementation、and space fetching technology. The voltage of the electric power is obtained from the high voltage transmission line by using the bipolar plate electric field induction. A capacitor is formed by erecting two plates parallel to the earth between the high-voltage line and the earth. The high voltage electric field between the high-voltage wire and the earth will cause a voltage difference between the poles of the capacitor, and this voltage difference is the driving voltage of the power pulse. The driving AC voltage is converted into DC by rectification, and the DC power is stored and output. The DC signal could control the MOSFET conduction and the shutdown, the output of DC power is converted to the power pulse signal. The signal causes the transistor to have two safe breakdown. Finally, the output pulse signal can drive the load.
