Abstract: An electrified powertrain system for a vehicle includes an electric machine coupled to a driveline. An inverter controller communicates directly with an auxiliary power module. An ignition module indicates either a key-on state or a key-off state. When the ignition module is in a key-off state, a low-power DC/DC converter generates an output voltage originating on the high-voltage DC bus having a magnitude sufficient to activate the inverter controller. The inverter controller detects a key-off uncontrolled generator (UCG) mode. The inverter controller directly communicates detection of the key-off UCG mode to the auxiliary power module. The inverter controller controls the inverter. The auxiliary power module supplies electric power to operate low-voltage electrically-powered powertrain actuators.

Abstract: An electrical connector assembly for an electronic module includes a plug element having a body including at least one terminal receiving section. The at least one terminal receiving section includes at least one locking tab element. At least one rigid bus bar terminal is mounted in the at least one terminal receiving section. The at least one bus bar terminal extends from a first end to a second end through a substantially rigid intermediate portion. The first end includes a locking tab member inter-engaging with the locking tab element and the second end includes a module connector member.

Abstract: Systems and methods for a fault protection are provided that can be implemented in a hybrid electric vehicle (HEV) to limit the magnitude of a current that flows when an AC-to-chassis fault (ACF) occurs between an AC connection and the chassis of the HEV. An electric machine having a winding, an inverter sub-module (ISM) having a first switch and a second switch, and fault protection elements (FPEs), coupled to the ISM, are provided. The winding is coupled to the ISM coupled via the AC connection. The FPEs can include, for example, first and second inductances. To limit the magnitude of the current, the current can be passed along a first current path that includes the second inductance when the first switch is closed, and can be passed along a second current path that includes the first inductance when the second switch is closed.
