decreation

常见例句

The decreation of the harmonic components is not apparent, but different between method 2 and method 1, due to the influence of switch losses of the IGBT, which is consisted of two IGBT and two FRD.
当仿真模型中的双向开关由两个IGBT和两个快恢二极管组成时，由于IGBT的开关损耗等因素对输入电流的影响，在仿真得到的输入电流频谱图中，谐波成分的减小不是很明显，但调制策略方式2和方式1的谐波成分仍有所不同。
