    Abstract: A vehicle includes an engine, transmission, auxiliary and high-voltage electrical loads, a drivetrain, and an electrical system. The electrical system, characterized by an absence of a DC-DC converter, includes a full-bridge active rectifier/inverter, a semi-active auxiliary rectifier, an MGU connected to the engine via the drivetrain, and a controller. The controller executes a first operating mode in which the bridge rectifier is disabled and the MGU operates as a motor to restart or assist the engine, and a second operating mode in which the MGU is a generator, with the rectifier/inverter powering the HV-ESS and HV electrical load. The auxiliary rectifier provides an auxiliary DC output voltage to the LV-ESS and auxiliary electrical load. Switches may be positioned between a DC bus connection point and the HV-ESS and LV-ESS, with a switch closed and another opened in the first operating mode, and vice versa in the second operating mode.

    Abstract: A powertrain is disclosed. A ring gear is attached to a first distal end of a crankshaft such that the ring gear and the crankshaft are rotatable in unison about a longitudinal axis. A motor-generator includes a motor/generator shaft rotatable about a first axis spaced from the longitudinal axis. A starter mechanism includes a first starter gear coupleable to the motor/generator shaft and rotatable about a second axis spaced from the longitudinal axis. The first and second axes are spaced and substantially parallel to each other. The first starter gear is movable along the second axis between a first position engaging the ring gear such that torque is transferred from the motor/generator shaft through the first starter gear and the ring gear to the crankshaft to start the engine, and a second position disengaged from the ring gear to rotatably disconnect the starter mechanism from the ring gear.

    Abstract: Method for voltage stabilization during an engine starting event of a vehicle includes receiving, at a switch device module, an active Start_ON signal from a starter solenoid module indicating initiation of the engine starting event. At the switch device module, an auxiliary electrical energy storage device (ESD) is electrically coupled to one or more auxiliary loads within a predetermined delay since the active Start_ON signal was received. A primary ESD and a starter motor are electrically decoupled from the one or more auxiliary loads only after the auxiliary ESD has been electrically coupled to the one or more auxiliary loads. In response to a predetermined condition occurring while the primary ESD and the starter motor are electrically decoupled from the one or more auxiliary loads, the primary ESD and the starter motor are electrically coupled to the one or more auxiliary loads.

    Abstract: A rotor for a permanent magnet synchronous machine that includes a rotor core structure. A first set of permanent magnets forms poles within the rotor core structure. Each pole includes a pair of permanent magnets from the first set of permanent magnets. A first set of apertures is formed in a first radial layer of the rotor core structure. Each pole includes a pair of apertures from the first set of apertures. The first set of permanent magnets is inserted within the first set of apertures. Each pair of permanent magnets within a pole cooperatively generates a magnetic field in a same direction within the pole. The magnetic field generated by a respective pair of magnets in a respective pole is opposite to a magnetic field generated by a pair of permanent magnets in an adjacent pole.
