简介：注：金星系列的直流型号均为两件装，即光源加镇流器。

Remarks: With the DC version of JX series, light source & control gears come separately.

由于发射器的载波泄漏会对线性度造成影响，论文提出了使用7位电流型DAC来校正上调制器的输出直流失调来提高载波抑制。

To prevent the carrier leakage caused by DC-offset, the 7-bits DAC is inserted to cancel this dc-offset.

根据变流器直流侧滤波元件，将谐波源分成电流型和电压型谐波源。

The harmonic source can be classified into current harmonic source and voltage harmonic source on the basis of a transformer with a filter component on its DC side.
