Abstract: A vehicle includes an electric machine, an IGBT, and a gate driver. The IGBT has a gate, an emitter, and a collector and is configured to flow an electric charge through a phase of the electric machine. The gate driver is configured to flow current onto the gate at a first level, and in response to a time integral of a voltage across the phase exceeding a predetermined level, transition from the first level to a second level less than the first level.

Abstract: A vehicle power stage assembly is disclosed which may include a power stage housing, a power stage supported by the housing, and a pair of stacked DC leadframes. The pair of stacked DC leadframes are of opposite polarity and spaced apart from one another. Each of the DC leadframes may extend from the power stage and each has distal and proximal ends. The spacing between the leadframes may be such that parasitic inductances associated with current flowing through each of the leadframes at least partially cancel one another. Each of the leadframes may define a first and second side surface opposite one another. The first side surfaces may be coplanar and the second side surfaces may be coplanar. A distance between the spaced apart pair of DC leadframes may be based on a preselected amount of current and a material of the DC leadframes.

Abstract: A vehicle powertrain includes an IGBT and a gate driver. The IGBT is configured to energize an electric machine. The gate driver is configured to apply an off voltage less than a threshold voltage onto a gate of the IGBT while the IGBT is operating in a saturation mode, and in response to expiration of a delay from a transition from saturation to linear mode, apply a voltage pulse above the off voltage to reduce flyback from the electric machine. The gate driver may be configured to, in response to expiration of a delay from a transition from saturation to linear mode, apply a voltage pulse above the off voltage and below the threshold to reduce flyback from the electric machine.

Abstract: A power switching circuit provides temperature compensation for an insulated gate power switching device. A timing circuit determines a switch timing signal comprising desired on and off switching times of the switching device. A temperature monitor quantifies a device temperature. A gate drive profile generator generates a switching device drive signal according to the switch timing signal and having a dv/dt phase and a di/dt phase. The drive signal has a profile during the di/dt phase that is adjusted in response to the device temperature, and the drive signal has a profile during the dv/dt phase that is not adjusted in response to the device temperature.

Abstract: A vehicle powertrain includes an IGBT that conducts current between a supply and load. The vehicle powertrain also includes a controller that applies voltage to a gate of the IGBT at a first level for a first duration that depends on a capacitance of the gate, and increases the voltage over a second duration based on a rate of change of the current falling below a threshold defined by a supply voltage for the load.

Abstract: A vehicle system includes a converter, outlets, and a switching arrangement electrically between the outlets and the converter. A controller is programmed to, responsive to a first request, operate the switching arrangement to electrically connect a line and a neutral to a first outlet and operate the converter to output single-phase power to the first outlet. Responsive to a second request, the controller is configured to operate the switching arrangement to electrically connect a plurality of lines and not the neutral to a second outlet, and operate the converter to output three-phase power to the second outlet.
