Description

用于电机的直流电压转换器-布置结构
技术领域
本发明涉及一种用于电机的直流电压转换器-布置结构。
背景技术
在电机中，定子叠片组通常用于驱动转子，其中，定子绕组通过电流引起磁场，该磁场在定子和转子之间产生扭矩，用于该转子的旋转驱动。
在电动车辆和混合动力车辆中，为了支持12V车载电网，通常使用直流电压转换器。直流电压转换器把直流电压转变为具有较高的、较低的或者逆反的电压水平的直流电压，这借助于周期性地工作的电子开关和借助于至少一个用于能量的暂存器来进行。作为暂存器或者为了绝缘，要么使用电感，要么使用（用于较高电压的）变压器。此外，电感或变压器还被需要用于滤除在直流电压转换器中产生的高频的电流分量。针对电感或变压器，要预备相当大的安装空间，此外，它们也在直流电压转换器中形成了相对高的成本份额。
发明内容
本发明的目的因此是，提供一种用于电机的直流电压转换器，其特别小地构造并且成本低廉。
该目的通过独立权利要求的主题得以实现。有利的实施方式是从属权利要求、后续的说明书以及附图的主题。
根据本发明的用于电机的直流电压转换器-布置结构包括直流电压转换器和定子，该定子带有一第一绕组和至少一个第二绕组，其中，第一绕组被设计用于运行电机，并且至少一个第二绕组被设计用于给直流电压转换器提供电感。
至少一个第二绕组可以装入到电机的定子的叠片组中，并提供附加的电感，直流电压转换器可以为了其运行而使用该电感。至少一个第二绕组的电感可以用作暂存器、用作绝缘部件和用作用于在直流电压转换器中产生的高频的电流分量的滤除元件。
所述绕组可以优选如此地布置在定子上，使得第二绕组的每个导体都与另一导体串联地连接，所述每个导体在轴向方向上延伸经过定子并且受到一极的磁场，所述另一导体对于转子的每次励磁和每个位置来说都遭受与第一导体的场相同的场。两个导体的连接以旋转轴线为参照优选在定子的一侧上进行。由此消除了在该导体回路中的感应电压，且在另一侧上在端部处不能测出电势差。至少一个第二绕组因而特别是很少受定子中的由电机的运行产生的磁通量的影响。
直流电压转换器的部件因而集成到定子中，由此可以利用已有的结构。特别地，至少一个第二绕组可以被用于定子的第一绕组的本来就存在的冷却系统冷却。
定子的或电机的其他也可用于直流电压转换器的结构例如是绕组技术构件、PCB-连接件、电源和微处理器。就此而言，根据一种实施方式特别地规定，直流电压转换器的功率电子器件集成到电机的逆变器的电路板中。
此外，定子还可以具有多个第二绕组。多个第二绕组分布在定子内部，并有助于使得各个导线内部的电流强度最小化或者保持特别小。
根据另一实施方式，至少一个第二绕组包括两个平行地伸展的线材或导体。通过两个相互平行地伸展的线材产生了变压器，这尤其对于采用高压系统的应用是有利的。采用该实施方式，在相应地调整第二绕组的情况下，也可以实现不等于1的变压比。
同样可以有利地规定，电机的星形接点提供节拍式的和受控的电压输出。这能以特别简单的方式实现逆变器与直流电压转换器的集成。
附图说明
下面借助示意图详述本发明的实施例。在此：
图1示出了根据本发明的带有第二绕组的直流电压转换器-布置结构的实施例的立体局部视图；
图2示出了根据图1的第二绕组的立体图；
图3示出了用于低压系统的直流电压转换器-布置结构的实施例的电气接线图；
图4示出了用于高压系统的直流电压转换器-布置结构的实施例的电气接线图；
图5示出了用于低压系统的直流电压转换器-布置结构的实施例的电气接线图；并且
图6示出了用于高压系统的直流电压转换器-布置结构的实施例的电气接线图。
具体实施方式
图1示出了电机的定子1的上面的部分，该机器未进一步被图1示出。该定子包括沿着其内圆周2布置的用于未示出的第一绕组的绕组槽3，该第一绕组用于运行电机。沿着定子2的外圆周4布置了用于给未被图1示出的直流电压转换器提供电感的第二绕组5。
如特别是由图2可见的那样，第二绕组5包括四个相互平行的以及平行于定子1的纵轴线而伸展的导体区段6，其中，每个导体区段6都包括四个相互平行的以及平行于该纵轴线而伸展的导体7或线材。所述导体区段6在定子1的彼此对置的端侧的端部上通过接片8相互连接。
图3示出了低压电网、例如48V电网，其具有带逆变器11的电机10的定子的第一绕组9的三个相u、v和w，其中，该电机10在此作为发电机工作，用于运行负载RL。在定子内部设置了电感L定子，该电感由在定子内部的第二绕组5形成，并供直流电压转换器使用。根据该实施例，电机10的星形接点用于提供节拍式的和受控的电压输出，由此提供了逆变器11与直流电压转换器的集成。
图4示出了高压电网HV，其具有带逆变器11的电机10的定子的第一绕组9的三个相u、v和w，其中，该电机10作为发电机工作，用于运行布置在低压电网LV中的负载RL。在定子内部布置了变压器12，该变压器把高压电网HV中的较高的直流电压转变为低压电网中的较低的直流电压，其中，变压器12—如通过图1所示的那样—由两个相互平行地伸展的导体或线材形成，并供直流电压转换器使用。根据该实施例，电机10的星形接点用于提供节拍式的和受控的电压输出，由此提供了逆变器11与直流电压转换器的集成。
图5示出了带有电感5的降压和升压斩波器形式的直流电压转换器18，该电感通过在定子中在第二绕组内的导体的、在图1中所示的布置结构形成。为了在负载16处由源15使得降压斩波器运行，无需开关14和电压源13。为了实现升压斩波器，需要源13和开关14，其中，省去了并联的电阻16和电压源15。
图6示出了带有变压器5的直流电压转换器19，该变压器通过在定子中在第二绕组内的导体的、在图1中描绘的布置结构形成。在该布置结构中，由高压电源17使得低压电网中的负载16运行。
