Zusammenfassung: | The invention relates to a control device (8) for an inverter (2) for supplying an electric machine (3), said control device (8) being designed to provide a pulse width modulated switching signal (15) at a carrier frequency in order to control switching elements (12) of the inverter (2), wherein the control device (8) is designed to determine a carrier frequency within the at least one operating range (22, 23) on the basis of operating point information describing an operating point defined by a rotational speed and a torque of the electric machine (3) such that the carrier frequency is reduced within the at least one operating range (22, 23) relative to a maximum carrier frequency operating point specifying a maximum carrier frequency within the operating range.
本发明涉及一种用于给电机(3)供电的逆变器(2)的控制装置(8),其中控制装置(8)设计成以载波频率提供脉宽调制开关信号(15)以控制逆变器(2)的开关元件(12),其中控制装置(8)设计成根据描述由电机(3)的转速和扭矩限定的操作点的操作点信息来确定至少一个操作范围(22、23)内的载波频率,使得载波频率在至少一个操作范围(22、23)内相对于在该操作范围中指定最大载波频率的最大载波频率操作点降低。 |
