The invention relates to a voltage conversion assembly in an electric drive system, which voltage conversion assembly can actuate a coupled electric machine in one operating mode and can convert an input DC voltage into an output DC voltage in the other operating mode. In order to convert an input DC voltage into an output DC voltage, a phase winding of the connected electric machine can be used as an inductor. In this case, the individual phase windings can be individually energized as a function of the rotor position and a target value specification of the total current.
本发明涉及一种在电驱动系统中的电压转换组件,该电压转换组件能够在一种运行模式中操控所联接的电机,并且能够在另一种运行模式中将输入直流电压转换为输出直流电压。为了将输入直流电压转换为输出直流电压,所联接的电机的相绕组能够用作电感。在此,各个相绕组能够根据转子位置以及总电流的目标值预设来分别地通电。
