The invention provides a control unit 1 which generates pulse width modulation (PWM) pulses for an inverter 2, in particular a drive train. The control unit has a noise reducer 3 configured to generate an opposing signal for active noise reduction. The noise reducer is configured to set a phase (deltatheta PWM) of the opposing signal as a function of a predefined PWM frequency (F) and/or rotational speed (omegam). The invention further relates to a drive train (10), to a motor vehicle (100) and to a method for operating a drive train (10).
本发明提出一种控制单元(1)，该控制单元用于产生用于逆变器(2)的、尤其驱动系(10)的逆变器(2)的PWM脉冲，该控制单元具有用于产生反信号以主动降噪的降噪装置(3)，其中该降噪装置(3)被适配成用于根据预先给定的PWM频率(F)和/或转速(ωm)来设定该反信号的相位(ΔθPWM)。本发明还提出了一种驱动系(10)、一种机动车辆(100)以及一种用于运行驱动系(10)的方法。
