Secondly, the lowduty cycle leads to the high voltage and current ripple, and enlarges the filter size.
整流输出的电压、电流脉动大，需要增大滤波器的体积；

Experimental results indicate that tiny feeding, low voltage, lowduty ratio and high frequency have important effects to increase the truing precision.
实验结果表明最后整形阶段的微小进给量及低电压、低占空比和高频率的电参数对提高整形精度具有重要作用。
