Description

用于电驱动装置的逆变器的半桥模块及逆变器
技术领域
本发明涉及一种用于电动车辆或混合动力车辆的电驱动装置的逆变器的半桥模块以及一种对应的逆变器。
背景技术
在现有技术中已知专有地或辅助地由作为驱动组件的一个或多个电动机器驱动的纯电动车辆以及混合动力车辆。为了给这样的电动车辆或混合动力车辆的电动机器供应电能,电动车辆和混合动力车辆包括电能储存器、尤其可再充电的电池。这些电池在此被设计为直流电压源,然而电动机器一般需要交流电压。因此在电动车辆或混合动力车辆的电池与电动机器之间通常连接有具有所谓的逆变器的功率电子设备。
这种逆变器通常包括半导体开关元件,这些半导体开关元件典型地由晶体管构成。在此已知进而提供不同集成度的半导体开关元件,尤其作为集成度低然而可扩展性高的分立的单个开关器,或者作为集成度高然而可扩展性低的桥模块,以及作为在集成度和可扩展性方面介于单个开关器与桥模块之间的半桥模块。三个半桥模块在此典型地构成逆变器,从而使逆变器因此被设计为三相的。
在DE 10 2006 050 291 A1中公开了一种电子组件,该电子组件包括半导体功率开关和半导体二极管。在此,半导体功率开关的底侧包括装配在载条的芯片区上的输出触点,并且半导体功率开关的顶侧包括控制触点和输入触点。半导体二极管的阳极触点被布置在半导体功率开关的输入触点上并且与该输入触点电连接。二极管的阴极触点与功率半导体开关的输出触点电连接。
DE 10 2006 008 632 A1公开了一种功率半导体构件,该功率半导体构件包括扁平导体框架、至少一个竖直的功率半导体器件和至少一个另外的电子构件。竖直的功率半导体器件具有第一侧和第二侧。至少一个第一接触面和至少一个控制接触面被布置在第一侧上,并且第二接触面被布置在第二侧上。至少一个另外的电子构件被布置在竖直的功率半导体器件的第二接触面上。
从DE 10 2015 012 915 A1中已知一种半导体模块,该半导体模块具有:至少一个第一半导体元件,该第一半导体元件具有带有至少一个第一电极的第一侧和带有至少一个第二电极的第二侧;以及至少一个第二半导体元件,该第二半导体元件具有带有至少一个第一电极的第一侧和带有至少一个第二电极的第二侧。第一半导体元件被布置在第二半导体元件上方,并且在第一半导体元件与第二半导体元件之间布置有导电的连接件,其中第一半导体元件的至少一个第二电极与导电的连接件机械连接且电连接,并且第二半导体元件的至少一个第一电极与导电的连接件机械连接且电连接。
从申请人还尚未公开的DE 10 2019 220 010.9中已知一种半桥模块,在该半桥模块中信号端子和功率端子全都被布置在基板的共用侧上并且被模制料包围。功率端子和信号端子都能够从基板的共用侧触及,使得这些功率端子和这些信号端子从该基板的共用侧看延伸穿过浇铸料,并且在其穿过浇铸料的穿通方向上看被布置在由该基板扩展出的底面内。
根据半导体开关元件在基础的基板上的具体布置,已知的逆变器具有各种缺点,例如散热不良、电流分布不均匀或结构空间需求较高。在此,改善散热通常导致结构空间需求更高并且反之亦然。电流分布更均匀同样导致散热恶化或同样导致结构空间需求更高并且反之亦然。也应注意由半导体开关元件的所选布置方式而引起的逆变器的电感特性。
发明内容
本发明的目的在于,提出一种用于电动车辆或混合动力车辆的电驱动装置的逆变器的改进的半桥模块。
根据本发明,该目的通过如下一种用于电动车辆或混合动力车辆的电驱动装置的逆变器的半桥模块来实现。
本发明涉及一种用于电动车辆或混合动力车辆的电驱动装置的逆变器的半桥模块,所述半桥模块包括:基板;布置在所述基板上的半导体开关元件、功率端子和信号端子,其中所述信号端子电连接至所述半导体开关元件,使得所述半导体开关元件能够藉由所述信号端子来切换,并且其中所述功率端子电连接至所述半导体开关元件,使得所述半导体开关元件允许或中断所述功率端子之间的电功率传输。根据本发明的半桥模块的突出之处在于,所述半导体开关元件部分地藉由接合线并且部分地藉由导体框架电接触。
因此根据本发明也提出一种适合在逆变器中使用的半桥模块,其中逆变器自身适合用于在电动车辆或混合动力车辆中给电动马达供应交流电压。半桥模块包括基板,该基板例如可以被设计为DBC(Direct Bonded Copper,直接敷铜)基板、AMB(Active MetalBrazing,活性金属钎焊)基板或IM(Insulated Metal,绝缘金属)基板。一方面在基板上布置有半导体开关元件(尤其晶体管和二极管),并且另一方面在基板上布置有相关联的功率端子和信号端子。基板优选被设计成具有各两个相反的侧边的矩形。基板必要时也可以被设计成正方形。信号端子在此用于切换半导体开关元件并且对应地与半导体开关元件的信号触点电连接。根据半导体开关元件的设计方案,于是可以通过给信号触点通电或者给切换区域
Figure BDA0003005239830000031
施加电压来以传导电流或阻断电流的方式切换半导体开关元件。功率端子本身与半导体开关元件的功率触点电连接,使得可以借助半导体开关元件将电功率从一个功率端子传输至另一个功率端子。藉由功率端子在此确保对用于驱动电动车辆或混合动力车辆的电动马达的电力供应。尤其在此设置有不同类型的功率端子,即正极端子、负极端子和相端子,其中正极端子用于馈送电流,而负极端子用于导出电流。最后,相端子用于通过提供交流电压来为电动马达实际供应电流。正极端子和负极端子优选被布置在基板的侧边缘附近,负极端子尤其被布置在基板的相对较短的侧边缘附近,而正极端子被布置在相对较长的侧边缘附近。半桥模块优选相应地包括两个正极端子和两个负极端子,其中然而也可以设置多于两个正极端子和两个负极端子,以便例如能够切换和传输更高的电流。相端子优选同样被布置在基板的相对较短的侧边缘附近、与负极端子相对。根据本发明的半桥模块的功率端子和信号端子全都可以从基板的共用侧(优选顶侧)触及。这意味着:所述功率端子和所述信号端子从所述基板的共用侧看延伸穿过所述浇铸料,并且从所述功率端子和所述信号端子穿过所述浇铸料的穿通方向看被布置在由所述基板扩展出的底面内。由此,功率端子可以彼此取向成使得半桥模块具有几纳亨数量级的换向单元(Kommutierungszelle)的较低漏电感以及同样信号端子的较低漏电感。这两者用于使切换损耗尽可能小的目的。功率端子和信号端子的这个设计方案的另一个优点在于,功率端子和信号端子不再朝向侧面延伸并因而被定位在由基板扩展出的底面之外。由此获得结构空间优势。
根据本发明,所述半导体开关元件部分地藉由接合线并且部分地藉由导体框架电接触,即,信号端子与信号区域或者功率端子与功率区域部分地藉由接合线或藉由导体框架电连接。由此获得非常灵活地将半导体开关元件布置在基板上的可能性的优点并且因此获得如下可能性:减少或避免上述现有技术中的缺点,尤其可以至少部分地打破电流分布、结构空间需求与散热之间的关系,因此上述特性之一的优化仅在很小的程度上或者甚至不会导致其余两个特性恶化。尽管由于导体框架能够实现相对均匀的电流分布并且还有利于引导相对较高的电流,但这些导体框架相对不灵活并且由于其结构形状而限制了在布置半导体开关元件方面的灵活性。相比之下,接合线相对灵活并且也能够与此相应地实现将半导体开关元件灵活地布置在基板上。而这些接合线在其确保电流均匀分布的可能性方面是受限的。半导体开关元件部分地通过接合线并且部分地通过导体框架进行电接触的根据本发明提出的组合可以组合在半桥模块上的接触的两种可能性的优点。
接合线在此可以根据需要(即根据要输送的电流强度)具有适合的直径和适合的材料。接合线同样不必强制性地具有圆形的横截面、例如直径为0.5mm至2.0mm的铜。也可以设想矩形或正方形的横截面。
导体框架在此由金属片冲压而成并且根据需要(即根据要输送的电流强度)具有适合的金属片厚度和适合的材料。导体框架优选具有三维轮廓,即这些导体框架具有:通过弯曲产生的凸起,这些凸起优选被布置在两个要连接的半导体开关元件或功率端子之间;以及通过弯曲产生的凹部,这些凹部优选被设置成与半导体开关元件或功率端子接触。每个导体框架都是一件式的并且可以取决于其几何形状使多个半导体构件和功率端子相互连接。尤其,通过相对较大面积和一件式的设计方式以及因此伴随通过导体框架内无连接点还实现特别均匀的电流分布。
半桥模块的基板上的半导体开关元件以及接合线和导体框架有利地借助于模制料来进行浇铸。这保护半桥模块免受环境影响并且尤其免受机械损坏。
根据本发明的一个优选的实施方式提出,所述半导体开关元件的信号触点藉由接合线电接触。由于信号触点一般不必施加有较高的电流或者甚至仅必须施加有电压并且因此电流的尽可能均匀的分布不具有或几乎不具有重要意义,因此在这种情况下可以通过借助于接合线进行电接触来确保半导体开关元件在任何情况下的可靠的可切换性,其中同时接合线是灵活的,使得其例如可以被布置在导体框架周围或者可以越过导体框架布置,因此在任何情况下都不限制相对不灵活的导体框架的布置。因此,并不限制导体框架在空间上以及在几何上的布置可能性。
根据本发明的另一个优选的实施方式提出,所述半导体开关元件的功率触点藉由所述导体框架电接触。由此获得的优点在于,导体框架在其均匀的电流分布以及其良好的导电性方面的优点与功率触点要馈入或要导出的一般较高的电流有关。此外,如果信号触点藉由接合线电接触,则由于接合线的灵活性而几乎不必考虑信号触点的电接触,因此几乎仅根据优化的电流分布、热发散及结构空间限制的需求来设计导体框架。导体框架还允许全面地接触功率触点,这不仅实现较小的电阻以及在半导体开关元件中改善的电荷载体分布,而且还允许从半导体开关元件到导体框架中并且从导体框架到周围环境中的热发散。
根据本发明的一个特别优选的实施方式提出,所述导体框架至少局部地具有比所述半导体开关元件更大的宽度。因此这确保了以尽可能小的电阻向半导体开关元件馈送电功率或从半导体开关元件导出电功率。以这种方式扩大的表面还改善了从半导体开关元件经由导体框架到周围环境中的散热。
根据本发明的另一个特别优选的实施方式提出,所述半桥模块包括高侧电路和低侧电路,其中所述高侧电路指配有恰好一个导体框架,并且其中所述低侧电路指配有恰好一个导体框架。因此,半桥模块由两个子电路(即高侧电路和低侧电路)构成。高侧电路在此指配有正极端子,并且低侧电路指配有负极端子。低侧电路和高侧电路是能够与相端子电连接的。通过现在高侧电路和低侧电路分别指配有恰好一个导体框架,导体框架可以相对扁平地设计,即该导体框架可以具有相对大的宽度和长度。这还进一步改善了导电性和散热。
根据本发明的另一个特别优选的实施方式提出,所述导体框架被设计成使其几何形状包含U形。已经证实这个设计方式在很大程度上是最佳的,这是因为仅在“U”形的端部区域或“U”形的支腿之间存在允许将接合线连接到信号端子的凹口。此外,导体框架可以具有最大的长度或宽度或面积。
根据本发明的另一个优选的实施方式提出,所述半导体开关元件被设计为具有绝缘栅电极的双极晶体管,并且/或者被设计为碳化硅-金属-氧化物-半导体-场效应晶体管。具有绝缘栅电极的双极晶体管在此通常也被已知为所谓的IGBT,并且碳化硅-金属-氧化物-半导体-场效应晶体管通常也被已知为所谓的SiC-Mosfet。这些类型的半导体开关元件也相对较好地适用于低损耗地且快速地切换较高的电流。
根据本发明的一个特别优选的实施方式提出,每个具有绝缘栅电极的双极晶体管都指配有续流二极管。续流二极管尤其在切换电功率时保护其相应所指配的、具有绝缘栅电极的双极晶体管免受电感性过电压的影响。
根据本发明的另一个优选的实施方式提出,所述半导体开关元件以平面的方式布置在所述基板的顶侧上。由此获得进一步改善的散热能力的优点。
根据本发明的另一个优选的实施方式提出,每个半导体开关元件相对于一个功率端子被布置成在几何上并且在电气上与至少一个另外的半导体开关元件相对于另一个功率端子相同。这意味着:半桥模块具有一个或多个对称轴线或镜像点,半导体开关元件和功率端子的布置在这些对称轴线或镜像点处成镜像。例如,第一半导体开关元件可以藉由导体框架或导体框架区段与正极端子电连接,并且第二半导体开关元件可以藉由几何上相同的导体框架或几何上相同的导体框架区段与另一个正极端子电连接。因此两种电连接具有相同电阻值。例如,第三半导体开关元件和第四半导体开关元件同样也可以藉由几何上相同的、然而可能镜像相反的导体框架或者几何上相同的、然而可能镜像相反的导体框架区段与两个负极端子电连接。这种较高的对称性实现非常均匀的电流分布。
根据本发明的另一个优选的实施方式提出,所述半桥模块包括两个附加的电端子,这些附加的电端子与所述半桥模块的电连接被设计为用于提供针对操控电流的返回布线。在此,在具有绝缘栅电极的双极晶体管中附加的电端子之一被用作所谓的开尔文发射器(Kelvin-Emitter),并且在碳化硅-金属-氧化物-半导体-场效应晶体管中附加的电端子之一被用作所谓的开尔文源(Kelvin-Source)。所谓的开尔文发射器和所谓的开尔文源都用作针对操控电流的返回导体。通过这种类型的接触使负载电流对操控电流的影响最小化。此外,功率端子结合两个附加的电端子中的一个电端子可以被用来实现电感短路检测。为此,优选地测量功率端子与附加的电端子之间的电压降。
操控电流在此被馈送给半导体器件的信号触点并且以传导电流或阻断电流的方式切换半导体器件。
本发明还涉及一种用于电动车辆或混合动力车辆的电驱动装置的逆变器,所述逆变器包括至少三个根据本发明的半桥模块。因此,结合根据本发明的半桥模块已经描述的优点也适用于根据本发明的逆变器。

具体实施方式
图1示例性且示意性地示出了根据本发明的用于电动车辆或混合动力车辆的电驱动装置的逆变器20的半桥模块1的可能的第一实施方式。半桥模块1由高侧电路1'和低侧电路1”组成。该半桥模块包括:基板2,该基板根据示例被设计为具有陶瓷性的载体板和两侧的铜涂层的DBC(Direct Bonded Copper,直接敷铜)基板2;以及以平面的方式布置在基板2的表面上的半导体开关元件3、续流二极管8、功率端子4、5、6和信号端子7,其中这些信号端子7分别具有信号端子触针7'。铜涂层在此的结构被设计成多个彼此分开的区段。此外,半桥模块1包括两个附加的电端子9,这些电端子与半桥模块1的电连接被设计为用于实现所谓的开尔文感测。因此使负载电流对操控电流的影响最小化。此外,可以藉由功率端子结合两个附加的电端子中的一个电端子来实现电感短路检测。为此,优选地测量功率端子与附加的电端子之间的电压降。两个附加的电端子9可以分别藉由为此设置的附加的电触针9'接触。功率端子4、5、6被设计为正极端子6、负极端子4和相端子5,并且至少正极端子6和相端子5藉由导体框架11电连接至半导体开关元件3,使得半导体开关元件3允许或中断功率端子4、5、6之间的电功率传输。为此,导体框架11在半导体开关元件3的顶侧上接触功率触点3”。如可以看到,导体框架11至少在半桥模块1的纵向中部区段中具有比半导体开关元件3更大的宽度。高侧电路1'和低侧电路1”各自指配有恰好一个导体框架11,其中每个导体框架11被设计成使其几何形状包含U形。这实现导体框架11的相对较小的电阻并且在半桥模块1中实现均匀的电流分布。信号端子7电连接至半导体开关元件3,使得半导体开关元件可以藉由信号端子7来切换。为此,信号端子7藉由接合线10与半导体器件3的信号触点3'电连接并且藉由另外的接合线10与导体框架11电连接,使得为了进行切换而供应给半导体开关元件3的信号触点3'的电流可以经由功率触点3”和导体框架11再次被引导返回。根据示例,半导体开关元件3被设计为所谓的具有绝缘栅电极的双极晶体管3,其也被已知为绝缘栅极型双极晶体管(insulated gate bipolar transistor,IGBT)。根据示例,每个具有绝缘栅电极的双极晶体管3各自指配有续流二极管8,以便在切换电功率时保护具有绝缘栅电极的双极晶体管3免受电感性过电压的影响,否则这些过电压可能毁坏具有绝缘栅电极的双极晶体管3。
图2示例性且示意性地示出了根据本发明的用于电动车辆或混合动力车辆的电驱动装置的逆变器20的半桥模块1的可能的第二实施方式。图2的半桥模块1与图1的半桥模块1的不同之处在于,半导体开关元件3的形式不是被设计为具有绝缘栅电极的双极晶体管3,而是被设计为碳化硅-金属-氧化物-半导体-场效应晶体管3,其也被已知为碳化硅金属氧化物半导体场效应晶体管(siliciumcarbid metal oxide semiconductor field effecttransistor,SiC MOSFET)。由此可以有利地省去设置续流二极管8,然而为了切换相等的电流强度,需要比具有绝缘栅电极的双极晶体管3数量更多的碳化硅-金属-氧化物-半导体-场效应晶体管3。对应地,图2的半桥模块具有总共八个半导体开关元件3,而不是仅具有四个半导体开关元件。信号端子7以及导体框架11的几何设计适配于这个更大数量的半导体开关元件3,其中然而为高侧电路1'仅设置一个单独的导体框架11,为低侧电路1”仅设置一个单独的导体框架11。根据图2的实施例,每个导体框架11也被设计成使其几何形状包含U形。
图3示例性且示意性地示出了根据本发明的用于电动车辆或混合动力车辆的电驱动装置的逆变器20的半桥模块1的可能的第三实施方式。图3的半桥模块1与图2的半桥模块1的不同之处在于导体框架11的几何形状。如可以看到,高侧电路1'和低侧电路1”的每四个碳化硅-金属-氧化物-半导体-场效应晶体管3分别相对于功率端子4、5(根据示例,相对于负极端子4和相端子5)在几何上和电气上被布置成相同的。通过由此得到的较大的对称性对应地还获得半桥模块1中的非常均匀的电流分布。导体框架11在几何上与半导体开关元件3的这种布置相适配,然而这些导体框架在这个实施例中还具有其几何形状包含的U形。
图4示例性且示意性地示出了根据本发明的用于电动车辆或混合动力车辆的电驱动装置的逆变器20的可能的实施方式。根据示例,逆变器20包括六个根据本发明的半桥模块1,其中每两个半桥模块1的相端子5藉由共用的第三汇流排11a接触。相比之下,对于所有六个半桥模块1,正极端子6以及负极端子4分别藉由共用的第一汇流排11b或共用的第二汇流排11c接触。借助于(在图4中未展示的)烧结层,半桥模块1被布置在被设计为水冷却器的冷却装置12上。
