    • In one aspect, an apparatus includes a motor and inverter configured to provide input power to the motor. The apparatus may also include a data store comprising at least one entry including a first torque command, a first motor speed, and a first DC voltage value, where the first torque command and the first motor speed and the first DC voltage value are associated with a first current output and a processor. The processor receives a torque input, a DC voltage input, and a motor speed input and identifies the current output associated with the torque input, the DC voltage input, and the motor speed input based on another motor speed different than the motor speed input and another DC voltage different than the DC voltage input and the motor speed input, and output the determined current output to cause the inverter to provide the input power to the motor.

    • Power inverter assemblies are provided herein for use with motor vehicles. An inverter assembly may have a symmetrical structure configured to convert DC input power to AC output power. The inverter assembly may include a housing enclosing a symmetrical DC input portion, a symmetrical AC output portion, a DC link capacitor, and a gate drive portion having a pair of power modules. The symmetrical DC input portion can include a DC input bus bar sub-assembly to which the DC link capacitor is coupled, and a second DC bus bar sub-assembly that may electrically couple the DC link capacitor with the power modules. The symmetrical AC output portion may include a three phase output AC bus bar sub-assembly to which the power modules can be electrically coupled. A cooling sub-assembly may be provided for cooling the power modules with fluid transfer using a coolant.
