Abstract: A vehicle powertrain has a power inverter that includes a load switch with a main emitter and a current mirror emitter, a variable resistor coupled between the current mirror emitter and the main emitter, and a controller. The controller may be configured to adjust a gate voltage based on a voltage across the variable resistor, and responsive to the gate voltage exceeding a Miller plateau gate voltage, increase a variable resistor resistance such that feedback increases as the load switch saturates.

Abstract: A vehicle powertrain includes a variable voltage converter, a bypass diode and a controller. The bypass diode may be coupled in parallel with the converter and configured to clamp an output of the converter to a battery voltage. The controller may be configured to, while in a boost mode and in response to a rate of change of a converter inductor current exceeding a boost threshold, open switches of the converter to divert propulsive energy through the bypass diode. The controller may also be configured to, while in buck mode and in response to a magnitude of a converter inductor current exceeding a buck threshold, open switches of the converter to divert regenerative energy through the bypass diode, while reversed biased, to the battery.

Abstract: A vehicle power system may include a gate driver configured to drive a traction gate and a generator gate corresponding to switches of a variable voltage controller such that the gates have alternating pulse width modulation ON periods. The gates may be driven in response to a throughput magnitude falling below a threshold. The gate driver may be further configured to drive the gates such that a duty cycle of one of the gates is zero in response to the throughput exceeding the threshold.

Abstract: A system of one or more computers can be configured to perform particular operations or actions by virtue of having software, firmware, hardware, or a combination of them installed on the system that in operation causes or cause the system to perform the actions. One or more computer programs can be configured to perform particular operations or actions by virtue of including instructions that, when executed by data processing apparatus, cause the apparatus to perform the actions. One general aspect includes a series-parallel electric vehicle drive system, including a controller commutatively coupled to at least one inverter circuit with a serial insulated gate bipolar transistor (IGBT) and a parallel IGBT. The system includes a dc power source connected to an inverter circuit and a winding of a motor connected to an output of the invert circuit, wherein the inverter circuit generates a motor control signal.

Abstract: A vehicle includes an electric machine configured to provide propulsive force to the vehicle, and a power inverter configured to supply power from a traction battery to the electric machine using a first and second switch configured as a half-bridge, wherein the first switch is controlled by a gate driver. The gate driver is configured to operate in a soft turn-off mode when a load current exceeds a threshold for a time period defined by a mask timer, operate in a fast turn-off mode when the load current is below the threshold, and in response to a turn-off request received prior to expiration of the mask timer after the load current exceeds the threshold, enable the soft turn-off mode.
