total harmonic distortion thd meaning in English

总谐波失真

Although dm can also solve the modulation time error , but the output waveforms can ’ t reach the industrial standard ( total harmonic distortion thd ) . considering this , a new control strategy called current optimal control ( coc ) is presented in paper . coc is that system samples the output value real time , comparing with expected value , considering all switching actions available then draw a concluding to decide which way would be fastest and best way to render system smooth
针对这一缺点,本文提出了一种更好的控制策略,电流最优delta调制,它是在电流滞环控制的基础上,根据电路的输出信号来分析,考虑所有可能的逆变器动作来决定选用哪一种开关转换方式能最快最平稳地达到预期值,采用的是一种电流预测控制手段,从而使输出波形的纹波最小。
