蓄电池供电的高压脉冲电源的研制

为满足野外实验需要,本文研制了蓄电池供电的高压脉冲电源系统.通过对逐级台阶升压构充电方式的理论分析,得到了储能电容器两端电压和充电电流的变化规律及充电效率与充电参数的关系.在理论分析的基础上,设计了基于计算机和单片机的自动化控制系统.为确保系统工作可靠,采取了高低压回路隔离、光电隔离、浮地及金属壳屏蔽等措施,提高系统的抗干扰能力.实验结果表明,实现了对电容器近似恒流的高效充电,控制系统工作稳定.目前该充电系统已应用于强流电子束加速器和爆磁压缩发生器研究中,作为初始能源,为相应的设备提供高压脉冲大电流,取得了良好的应用效果.

Design of high voltage pulsed power supply using storage battery as primary energy source

To satisfy the request of field experiment,a more compact and smaller pulsed power supply system using storage battery as primary energy source is designed.The law of the change of the charging current and capacitor voltage and the relationship of the charging efficiency and circuit parameters are gained in the theoretical analysis,which provides the theoretical basis of the design. In order to ensure the safety of operators and to automate the system control,the control system is governed by computer.Some ...
