摘要
为进一步研究受控核聚变,EAST托卡马克将采用3.7GHz低杂电流驱动系统。本文根据3.7GHz低杂波相位控制系统的鉴相要求,采用先下变频,再用数字正交鉴相的设计方案,实现了相位的高精度测量。
A 3.7GHz Lower Hybrid Current Drive （LHCD） system will be implemented on EAST Tokomak for further research on controlled nuclear fusion. This paper presents the design of phase detection according to the requirement of 3. 7GHz Lower Hybrid Current Drive phase control system. First frequency is down converted, then it uses digital I/Q phase discrimination to realize high-precision phase measurement.
