传动装置12可包括行星齿轮单元(未示出)并可操作为无级变速器，而不具有任何固定传动比或阶梯传动比。传动装置12还可包括单向离合器(O.W.C)和发电机制动器33。O.W.C可连接到发动机20的输出轴，以控制输出轴的旋转方向。O.W.C可防止传动装置12反向驱动发动机20。发电机制动器33可连接到第二电机24的输出轴。可启用发电机制动器33以进行“制动”或者防止第二电机24的输出轴旋转。可选地，O.W.C和发电机制动器33可由实现发动机20和第二电机24的控制策略来代替。传动装置12可连接到驱动轴46。驱动轴46可通过差速器50连接到一对驱动轮48。传动装置的输出齿轮(未示出)可协助在传动装置12与驱动轮48之间传递扭矩。传动装置12还可与热交换器49或自动变速器的流体冷却器(未示出)连通，以冷却传动装置的流体。

车辆16可包括车辆系统控制器(VSC)60，VSC 60与其它车辆系统和控制器进行通信，以协调车辆16的操作。尽管示出为单个控制器，但是预期VSC 60可包括多个控制器，以根据总体车辆控制逻辑或软件来控制多个车辆系统和部件。
车辆控制器(诸如VSC 60和TCM 58)可包括彼此配合以执行车辆操作的各种配置的微处理器、ASIC、IC、存储器(例如，闪存、ROM、RAM、EPROM和/或EEPROM)以及软件代码。控制器还可包括预定数据或“查找表”，所述预定数据或“查找表”可从存储器中获取并且可以是基于计算和测试数据的。控制器可使用该预定数据以便于车辆操作的控制。VSC 60可通过使用总线协议(诸如，CAN和LIN)的一个或更多个有线或无线连接而与其它车辆系统和控制器(例如，BECM 54和TCM 58)通信。VSC 60可接收表示传动装置12的当前位置(例如，驻车挡、倒车挡、空挡或前进挡)的输入(PRND)。VSC 60还可接收表示加速踏板位置的输入(APP)。VSC 60可向TCM 58提供表示期望的车轮扭矩、期望的发动机转速和发电机制动器命令的输出，并且向BECM 54提供接触器控制。

电池52可经由充电端口66周期性地从外部电源或电网接收AC电能。车辆16还可包括从充电端口66接收AC电能的车载充电器68。充电器68可具有AC/DC转换能力，以将接收到的AC电能转换为适合于在再充电操作期间为电池52充电的DC电能。尽管以PHEV为背景进行示出和描述，但是预期可在其它类型的电气化车辆(诸如，FHEV或BEV)的情况下实现逆变器56。
参照图2，示出了VVC 10和逆变器56的电路图的示例。VVC 10可包括用于提升输入电压(V_bat)以提供输出电压(V_dc)的第一开关单元70和第二开关单元72。第一开关单元70被示出为具有以极性对调的方式并联连接(本文中称为反并联(anti-parallel))到第一二极管76的第一晶体管74。第二开关单元72被示出为具有反并联连接到第二二极管80的第二晶体管78。晶体管74和78中的每个都可以是一种可控开关(例如，绝缘栅双极型晶体管(IGBT)或场效应晶体管(FET))。另外，晶体管74和78中的每个均可由TCM 58单独控制。电感器组件14被描绘为串联连接在电池52与开关单元70和72之间的输入电感器。当供应电流时，电感器组件14可产生磁通。当流过电感器组件14的电流变化时，产生随时间变化的磁场并感应出电压。VVC 10的其它实施例可包括替代的电路配置(例如，多于两个开关)。

可使用液体热管理系统、空气热管理系统或本领域已知的其他方法来加热和/或冷却VVC和逆变器的部件。在液体热管理系统的一个示例中，热板可与VVC或逆变器的部件热连通。诸如受压系统(pressurized system)的系统可控制冷却剂经过热板的流动，以协助消散来自部件的热，诸如，在电压转换期间产生的热。热管理系统可与电力模块组件布置在一起或者可由电力模块组件支撑，使得热板与部件热连通以便于通过冷却剂对其进行冷却。
图3示出了用于电气化车辆的电力模块组件(在此统称为电力模块组件200)的一部分的示例。电力模块组件200可包括安装至基部单元组件206的上部框架单元204。如以下进一步描述的，在上部框架单元204中可容纳一个或更多个功率级。多种布置可适用于基部单元组件206以协助将冷却剂分配至上部框架单元204，从而协助管理被容纳在上部框架单元204中的功率级的热状况。
基部单元组件206可以是模块化的并包括操作为集合管的多个部件，所述多个部件用于将冷却剂输送至上部框架单元204。例如，图4A示出了可包括多个部件的基部单元组件206的示例。基部单元组件206可包括基部单元210、中部单元212以及上部单元214。基部单元210可包括将第一室218和第二室220隔开的分隔部216。入口224和出口226可安装到基部单元210。入口224可通向第一室218而出口226可通向第二室220。基部单元210可限定围绕基部单元210的周界延伸并与基部单元210的边缘232间隔开的脊(ridge)230。例如，脊230可与边缘232间隔开，使得中部单元212和上部单元214可安放在脊230上并安放在基部单元210内。
