抑制输入 meaning in Chinese

inhibiting input

To reduce the harmonics in the line current , the random pwm mode is adapt . related to the typically constant pwm carrier frequency and its high harmonics , modulation of this frequency can be used to decrease emi and cost no more gain
为了抑制输入电流中一些幅值较大的谐波成分，利用dsp控制的特点，电路采用了随机pwm方式，在不增加系统成本的前提下，有效地抑制了输入电流的高次谐波含量。
