摘要
以同步加速器环磁铁的激励为主要对象，提出了在大电感负载中产生平顶平底脉冲大电流的一个新的方案．主要思想是：采用两路直流电源，一路供给平底电流，两路串联供给平顶电流．一个充以适当高电压的电容与负载谐振放电，把负载电流从平底快速推到平顶；下降阶段中，这个电容与负载谐振使负载电流又快速地下降到平底，并回收了负载电感中储存的磁场能量．以若干可控硅及二极管的通断来实现各个阶段之间的相互衔接．文中给出了近似计算公式及一个具体实例的计算结果．
With the drive of synchrotron ring magnets as the main target, a new scheme is proposed for producting pulsed large currents with flat top and bottom in a large inductance loading. The main idea is to use two DC power supplies, one supplying the bottom current, and the two in series supplying the top current. One capacitor charged wiht a proper high voltage resonates with the loading inductance and dischargies, which quickly drives the loading current from the bottom to the top. In the falling stage, this capacitor resonating with the loading, makes the current drop quickly to the bottom again , and recovers the magnetic energy stored in the loading inductance. Some thyristors and diodes are used for conducting or interrupting to realize the joining of the stages.Approximate formulae and calculation results of one concrete example are given.
