LC串联谐振恒流充电系统

Constant current charging machine using LC series resonance

传统的RC恒压回路对大容量电容器组充电时存在充电时间长、效率低等问题。为此,利用LC串联谐振恒流概念,针对100MW红宝石激光器的要求,研制了LC串联节振恒流充电机,两年多的运行表明系统性能稳定可靠。

In charging the large capacity of capacitor bank, the traditional RC constant voltage charging circuit has the inherent shortcomings of long charging period and low efficiency. To get rid of these shortcomings and perfectly to meet the requirements of 100 MW ruby laser, the LC series resonance constant current charging machine was developed by taking advantage of the constant current source using LC scries resonance network. Over two years running this machine has been proved to be stable and reliable in performance.
