在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。本申请实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的，不应理解为对本申请实施例的限定。此外在上下文中，当提到一个元件被形成在另一个元件“上”或“下”时，其不仅能够直接形成在另一个元件“上”或者“下”，也可以通过中间元件间接形成在另一元件“上”或者“下”。术语“第一”、“第二”等仅用于描述目的，并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。可以根据具体情况理解上述术语在本申请中的含义。
图1是本申请实施例提供的一种电机控制器的爆炸图。图2是本申请实施例提供的一种功率电路板的结构示意图。图3是本申请实施例提供的一种功率电路板的爆炸图。参见图1-图3，该电机控制器包括功率电路板1，功率电路板1包括线路板11以及多个桥臂12；线路板11包括相对设置的安装面和非安装面，桥臂12设置在安装面所在平面上；桥臂12包括上桥臂121和下桥臂122，每个上桥臂121和每个下桥臂122中均包括多个分立的功率管；功率电路板1还包括埋设于线路板11内的多个第一铜排14A以及多个第二铜排14B；第一铜排14A和上桥臂121一一对应，第一铜排14A与同一个上桥臂121中的多个功 率管的第一极电连接；第二铜排14B和下桥臂122一一对应，第二铜排14B与同一个下桥臂122中的多个功率管的第二极电连接；功率电路板1还包括埋设于线路板11内的U相铜排131U、V相铜排131V以及W相铜排131W，设置为输出三相交流电。其中，线路板11包括电路基板，桥臂12可以为半桥。
继续参见图1，电机控制器还包括控制电路板6、屏蔽板5以及驱动电路板4，它们的实现方式可根据实际情况以及相关技术设置，此处不作限定。可选的，控制电路板6可以通过螺栓固定在屏蔽板5上，驱动电路板4可以通过螺栓固定在屏蔽板5的另一侧。如此，安装工艺简单，有利于提高安装效率。
图1中仅示例性示出了功率电路板1上设置有三个桥臂12，但并非对本申请的限定，可根据实际情况设置桥臂12的数量。为说明U相铜排131U、V相铜排131V以及W相铜排131W与功率管的连接情况，下面以功率电路板1上设置有三个桥臂12为例进行说明。示例性的，U相铜排131U、V相铜排131V以及W相铜排131W分别对应一个桥臂12，U相铜排131U与其对应的上桥臂121中的多个功率管的第二极电连接，且与其对应的下桥臂122的多个功率管的第一极电连接；V相铜排131U与其对应的上桥臂121中的多个功率管的第二极电连接，且与其对应的下桥臂122的多个功率管的第一极电连接；W相铜排131U与其对应的上桥臂121中的多个功率管的第二极电连接，且与其对应的下桥臂122的多个功率管的第一极电连接。当功率电路板1上设置有其它数量的桥臂12时，可根据实际情况设置U相铜排131U、V相铜排131V以及W相铜排131W与功率管的连接，只要可实现三相交流电输出即可。
在线路板11的制备过程中，第一铜排14A、第二铜排14B、U相铜排131U、V相铜排131V以及W相铜排131W预埋入线路板11中，即上述多个铜排和线路板11一体成型，如此，又可省去上述多个铜排与线路板11的装配步骤。并且，相较于铜排和线路板11通过螺栓连接，铜排预埋的方式可使铜排和线路板11的连接方式更可靠，进而确保震动环境下上述多个铜排和线路板11的良性电连接，提高耐震性能。其中，第一铜排14A设置为连接正直流母线，第二铜排14B设置为连接负直流母线，U相铜排131U、V相铜排131V以及W相铜排131W设置为输出三相交流电。在一实施例中，埋设于线路板11中的第一铜排14A、第二铜排14B、U相铜排131U、V相铜排131V以及W相铜排131W可以承载大电流，有利于增强功率电路板1的载流能力。

继续参见图3，功率电路板1还可以包括保护电路18、信号端子17以及吸收回路，其中，保护电路18设置为保护功率管的安全可靠工作，信号端子17设置为与驱动电路板4的信号交互，吸收回路设置为吸收功率回路中的杂散电感引起的电压尖峰与电流尖峰，可提高系统性能，增强系统的电磁兼容能级。
本申请实施例提供的电机控制器，通过采用分立的功率开关器件并联实现一个大功率器件的功能，使得可根据系统功率等级灵活控制一个大功率器件中并联的功率开关器件的数量，从而控制成本，并且可根据电机控制器自身尺寸要求以及功率电路板上其它器件分布情况合理布局多个分立的开关器件，解决由于采用功率器件模组带来的难以控制成本、不利于合理布局的问题，实现根据系统功率等级控制成本、合理布局，以及减小体积的效果。
在上述技术方案的基础上，继续参见图2和图3，可选的，U相铜排131U、V相铜排131V以及W相铜排131W均包括一体成型的第一导电结构131和第二导电结构132，或U相铜排131U、V相铜排131V以及W相铜排131W均包括焊接于一体的第一导电结构131和第二导电结构132，第一导电结构131和第二导电结构132相互垂直；第一导电结构131至少部分埋设于线路板11内，第二导电结构132裸露于线路板11外；第二导电结构132上设置有第一螺纹孔1321，第二导电结构132通过第一螺纹孔1321与电机的螺栓电连接。
线路板11上可以设置第一通孔112，第二导电结构132通过第一通孔112穿出线路板11，裸露在线路板11外。
当将电机控制器与电机电连接时，可将电极的U相电流输入端连接的螺栓与U相铜排131U上的第一螺纹孔1321配合、将电极的V相电流输入端连接的螺栓与V相铜排131V上的第一螺纹孔1321配合、以及将电极的W相电流输入端连接的螺栓与W相铜排131W上的第一螺纹孔1321配合。
相比于第一导电结构131和第二导电结构132通过螺栓连接，第一导电结构131和第二导电结构132一体成型或焊接于一体，有利于减少装配步骤，还可确保震动环境下第一导电结构131和第二导电结构132的良性电连接，提高耐震性能。
继续参见图2和图3，可选的，功率电路板1还包括电流传感器15，电流传感器15套设在第二导电结构132上。

功率管布置在第一铜排14A、第二铜排14B、U相铜排131U、V相铜排131V以及W相铜排131W之上，则功率管损耗产生的热量可以传递至上述铜排上，而上述铜排的下表面裸露在外，靠近散热器2，使得功率管损耗产生的热量可以通过上述铜排传递到散热器2上进行散热，如此，便于热量的及时流通，增强功率电路板1的整体散热能力。
在一实施例中，线路板11上还可以设置第四固定孔111，相应的，散热器2上可以设置第二螺纹孔21，功率电路板1和散热器2通过穿过第四固定孔111和第二螺纹孔21的固定螺栓16固定。图1中仅示例性示出了第四固定孔111以及第二螺纹孔21的数量均为12个，但并非对本申请的限定，可根据实际情况设置。

在一实施例中，第一导热绝缘垫的上表面与功率电路板1的非安装面接触，第一导热绝缘垫的下表面与散热器2朝向功率电路板1的表面接触。一方面，第一导热绝缘垫具有导热作用，有利于将功率电路板1上的热量传导至散热器2，进而增强散热能力；另一方面，第一导热绝缘垫具有绝缘作用，可保证功率电路板1绝缘耐压，使得功率电路板1的可靠性更高。
继续参见图1，可选的，电机控制器还包括电容3，电容3设置在散热器2背离功率电路板1的一侧。可选的，散热器2和电容3之间设置有第二导热绝缘垫(图)。在一实施例中，第二导热绝缘垫的上表面与散热器2背离功率电路板1的表面接触，第二导热绝缘垫的下表面与电容3朝向散热器2的表面接触。
将功率电路板1和电容3分设于散热器2的两侧，使得散热器2不仅可以 给功率电路板1散热，还可以给电容3散热，有利于提高电机控制器的整体散热能力。
可选的，电容3为集成式薄膜电容3。
相比于采用多个分立的电容3，采用集成式薄膜电容3，可使电容3结构更紧凑，有更好的电气性能和抗震能力。
继续参见图1，可选的，集成式薄膜电容3的封装壳的一个侧边设置有多个突出的第一耳部31和多个突出的第二耳部32，第一耳部31与集成式薄膜电容3的第一端电连接，第二耳部32与集成式薄膜电容3的第二端电连接；第一铜排14A以及第二铜排14B均包括一体成型的第三导电结构141和第四导电结构142，或第一铜排14A以及第二铜排14B均包括焊接于一体的第三导电结构141和第四导电结构142；第三导电结构141中的至少部分埋设于线路板11内，第四导电结构142裸露于线路板11外；第一铜排14A和第一耳部31一一对应，第一铜排14A的第四导电结构142中的至少部分与第一耳部31抵接；第二铜排14B和第二耳部32一一对应，第二铜排14B的第四导电结构142中的至少部分与第二耳部32抵接。

在一实施例中，第四导电结构142的形状、第一耳部31以及第二耳部32的形状，可根据实际情况设置，此处不作限定。示例性的，如图1和3所示，第四导电结构142可以呈“L”型，第一耳部31以及第二耳部32可以呈“台阶”状。
相比于第三导电结构141和第四导电结构142通过螺栓连接，第三导电结构141和第四导电结构142一体成型或焊接于一体，不仅有利于减少装配步骤，还可确保震动环境下第三导电结构141和第四导电结构142的良性电连接，提高耐震性能。
为划分第三导电结构141和第四导电结构142，图3在第三导电结构141和第四导电结构142的连接处画出一条虚线，但其并非实体结构。
继续参见图1，可选的，第一耳部31上设置有第一固定孔311，第二耳部32上设置有第二固定孔321；第四导电结构142上设置有第三固定孔1421；第一铜排14A和第一耳部31通过穿过第一固定孔311和第三固定孔1421的螺栓固定；第二铜排14B和第二耳部32通过穿过第一固定孔311和第三固定孔1421 的螺栓固定。第二铜排14B和第二耳部32通过穿过第二固定孔321和第三固定孔1421的螺栓固定。如此，不仅实现了功率电路板1与电容3的装配，还可保证第一铜排14A与第一耳部31的可靠接触电连接，以及保证第二铜排14B与第二耳部32的可靠接触电连接，进而提高耐震动性。
在一实施例中，集成式薄膜电容3的封装壳上还可以设置第五固定孔33，散热器2上还可以设置第三螺纹孔22，集成式薄膜电容3和散热器2通过穿过第五固定孔33和第三螺纹孔22的螺栓固定。
